Stop angle or protractor? (Note: The stop angle was made by the Secretary's great-grandfather. The protractor comes from a modern workshop supplier.)
Digging through some archive shots (as it's raining again)... One of those flight shots where you've get several pretty much identical, apart from the angle of the wings. I got my protractor out and it's a different shot to the one I posted three years ago.

Do you know what your child’s most annoying phrase is? It’s probably, “summer is over.” This is the time when back-to-school sales kick off long before classes do. If you know what you need in advance, you’ll be able to save significant money by taking advantage of these sales.
To do well in school, students must have all of the necessary supplies. Students can’t buy their own supplies, which means, at least to a certain extent, their success is dependent on their parents.
Different teachers request different supplies, making it difficult to have all the right supplies.
Some basic items are:
Pencils
Notebook
Crayons
Erasers
Sharpeners
Highlighters
Protractor
Ruler

(Note: In the angle unit "Artillereristische Strich" (or "Artilleriepromille" in Switzerland), which is common in artillery, the full circle is divided into 6,400 "Artilleristische Strich". An angle of 30 degrees thus corresponds to 533.3 "Artilleristische Strich".)
quando sono salito a bordo della Royal Clipper mi ha fatto piacere trovarci oltre che il sestante (del quale vi ho già parlato) anche il goniometro, che vedete nella foto. E' uno strumento che misura gli angoli ed è con questo strumento che il vostro amico Marino ha fatto i suoi primi (ed anche gli ultimi) punti nave. Voi vi chiederete: cos'è il Punto Nave? E' il punto preciso dove si trova la nave in quel momento. Si, figuratevi se non lo so, adesso il punto nave è fornito continuamente dal GPS, ma sapete che io sono un romanticone e mi piace ricordare gli inizi della mia vita da innamorato del mare. Adesso una nave si può comandare da un ufficio situato a mille e più miglia di distanza, ma 12 anni fa, quando sono salito con gioia sulla Royal, c'erano già i GPS, ma c'erano ancora il sestante per fare il punto nave con le stelle e i due goniometri (uno sull'aletta di dritta (destra) e l'altro sull'aletta di sinistra a seconda che la costa si trovasse a dritta (destra) o sinistra. Quand'avevo il mio turno sul Ponte di Comando della Royal Clipper, avevo continuamente il punto nave fornito dal GPS, ma ogni tanto andavo sull'aletta a misurarmi gli angoli che sempre mi confermavano che quanto diceva il GPS era vero. Come lo si usa sto benedetto goniometro? come vedete è una ruota fissata su una bussola graduata da 0 a 360 gradi, traguardando fra le 2 piccole astine innalzate un punto preciso come un faro o un punto definito (sempre marcati sulle carte geografiche di cui la nave è fornita) nel goniometro leggerete l'angolo corrispondente, ne traguarderete un altro posto ad una certa distanza (90 gradi è l'ottimale) avrete due linee che, riportate sulla carta geografica della zona, si intersecano. Il punto dove si trova la nave è proprio nell'incrocio delle 2 linee.
Adesso vi devo chiedere scusa, perchè lo so che vi ho fatto una testa così, ma pensate che tutto ciò che ho scritto qui mi ha regalato un momento piacevole, non vi ho detto che sono innamorato del mare e della navigazione?
Grazie infinite e un grosso bacione a chi mi ha letto fino in fondo, vi voglio bene
when I was onboard the Royal Clipper I was pleased to find not only the sextant (which I have already told you about) but also the Protractor, thath you see in the photo. It is an instrument for measuring angles and it is with this instrument that your friend Marino made his first (and also his last) Ship's Point. Here you could ask: what is the Ship's Point? It is the precise point where the ship is at that moment. Sure, I know that now the ship's position is continuously provided by GPS, but you know that I am romantic and I love to remember the beginnings of my sea life as a great sea's lover. Now a ship can be direct from an office located a thousand or more miles away, but 12 years ago, when I joyfully boarded the Royal, there were already GPS, but there were still sextants to take ship position with the stars and the two protractors (one on the starboard (right) vane and the other on the port vane depending on where the coast was located. When I had my turn on the Command Bridge of the Royal Clipper, I continuously had the ship's point provided by the GPS, but every now and then I went to the side wing of the Bridge to measure the angles which always confirmed to me that what the GPS said was true. How do you use this blessed protractor? as you can see it is a fixed wheel on a compass graduated from 0 to 360 degrees, looking between the 2 small irons to a precise point such as a lighthouse or a defined point (always marked on the geographical maps supplied with the ship) in the protractor you will read the corresponding angle, you will look at another place at a certain distance (90 degrees is optimal) you will have two lines which, shown on the geographical map of the area, intersect. The point where the ship is located is right at the intersection of the 2 lines.
Now I have to apologize to you, because I know I made you mad for reading all, but you know that everything I wrote here gave me a pleasant moment, didn't I tell you that I'm in love with the sea and sailing?
Thank you so much and a big kiss to those who had patience to read me to the end, I love you

Grew up in a classic geometrical home.
Triangle on top, square on the bottom.
Lots of rigid right angles.
Went to a typical elementary school for shapes.
Long rectangle two parallel sides
Half long, half short.
But, the cloudy rectangle
Was quite different from all of his friends
Who, of course, wanted to grow up to be either
Architects or fixtures in buildings or
Colorful abstract modern art paintings
Measurable by protractors and rulers.
Instead, this polygon
Wanted to stop being so defined
Grow a little fluff on top and in back
Float away as part of the sky.
Like a passing thought
When you remember your childhood
But instead of remembering
The space that confined you
The definitions that defined you
The facts that seemed to bind you
You remember the feeling of being
Loved and weightless
Limitless and immeasurable
Like a line that goes on on in both directions forever.
In this very vast blue world.

The common starling (Sturnus vulgaris), also known as the European starling, or in the British Isles just the starling, is a medium-sized passerine bird in the starling family, Sturnidae. It is about 20 cm (8 in) long and has glossy black plumage with a metallic sheen, which is speckled with white at some times of year. The legs are pink and the bill is black in winter and yellow in summer; young birds have browner plumage than the adults. It is a noisy bird, especially in communal roosts and other gregarious situations, with an unmusical but varied song. Its gift for mimicry has been noted in literature including the Mabinogion and the works of Pliny the Elder and William Shakespeare.
The common starling has about a dozen subspecies breeding in open habitats across its native range in temperate Europe and western Asia, and it has been introduced to Australia, New Zealand, Canada, United States, Mexico, Peru, Argentina, the Falkland Islands, Brazil, Chile, Uruguay, South Africa and Fiji. This bird is resident in southern and western Europe and southwestern Asia, while northeastern populations migrate south and west in winter within the breeding range and also further south to Iberia and North Africa. The common starling builds an untidy nest in a natural or artificial cavity in which four or five glossy, pale blue eggs are laid. These take two weeks to hatch and the young remain in the nest for another three weeks. There are normally one or two breeding attempts each year. This species is omnivorous, taking a wide range of invertebrates, as well as seeds and fruit. It is hunted by various mammals and birds of prey, and is host to a range of external and internal parasites.
Large flocks typical of this species can be beneficial to agriculture by controlling invertebrate pests; however, starlings can also be pests themselves when they feed on fruit and sprouting crops. Common starlings may also be a nuisance through the noise and mess caused by their large urban roosts. Introduced populations in particular have been subjected to a range of controls, including culling, but these have had limited success except in preventing the colonisation of Western Australia. The species has declined in numbers in parts of northern and western Europe since the 1980s due to fewer grassland invertebrates being available as food for growing chicks. Despite this, its huge global population is not thought to be declining significantly, so the common starling is classified as being of least concern by the International Union for Conservation of Nature.
The common starling is 19–23 cm (7.5–9.1 in) long, with a wingspan of 31–44 cm (12–17 in) and a weight of 58–101 g (2.0–3.6 oz). Among standard measurements, the wing chord is 11.8 to 13.8 cm (4.6 to 5.4 in), the tail is 5.8 to 6.8 cm (2.3 to 2.7 in), the culmen is 2.5 to 3.2 cm (0.98 to 1.26 in) and the tarsus is 2.7 to 3.2 cm The plumage is iridescent black, glossed purple or green, and spangled with white, especially in winter. The underparts of adult male common starlings are less spotted than those of adult females at a given time of year. The throat feathers of males are long and loose and are used in display while those of females are smaller and more pointed. The legs are stout and pinkish- or greyish-red. The bill is narrow and conical with a sharp tip; in the winter it is brownish-black but in summer, females have lemon yellow beaks while males have yellow bills with blue-grey bases. Moulting occurs once a year- in late summer after the breeding season has finished; the fresh feathers are prominently tipped white (breast feathers) or buff (wing and back feathers), which gives the bird a speckled appearance. The reduction in the spotting in the breeding season is achieved through the white feather tips largely wearing off. Juveniles are grey-brown and by their first winter resemble adults though often retaining some brown juvenile feathering, especially on the head. They can usually be sexed by the colour of the irises, rich brown in males, mouse-brown or grey in females. Estimating the contrast between an iris and the central always-dark pupil is 97% accurate in determining sex, rising to 98% if the length of the throat feathers is also considered. The common starling is mid-sized by both starling standards and passerine standards. It is readily distinguished from other mid-sized passerines, such as thrushes, icterids or small corvids, by its relatively short tail, sharp, blade-like bill, round-bellied shape and strong, sizeable (and rufous-coloured) legs. In flight, its strongly pointed wings and dark colouration are distinctive, while on the ground its strange, somewhat waddling gait is also characteristic. The colouring and build usually distinguish this bird from other starlings, although the closely related spotless starling may be physically distinguished by the lack of iridescent spots in adult breeding plumage.
Like most terrestrial starlings the common starling moves by walking or running, rather than hopping. Their flight is quite strong and direct; their triangular-shaped wings beat very rapidly, and periodically the birds glide for a short way without losing much height before resuming powered flight. When in a flock, the birds take off almost simultaneously, wheel and turn in unison, form a compact mass or trail off into a wispy stream, bunch up again and land in a coordinated fashion. Common starling on migration can fly at 60–80 km/h (37–50 mph) and cover up to 1,000–1,500 km (620–930 mi).
Several terrestrial starlings, including those in the genus Sturnus, have adaptations of the skull and muscles that help with feeding by probing. This adaptation is most strongly developed in the common starling (along with the spotless and white-cheeked starlings), where the protractor muscles responsible for opening the jaw are enlarged and the skull is narrow, allowing the eye to be moved forward to peer down the length of the bill. This technique involves inserting the bill into the ground and opening it as a way of searching for hidden food items. Common starlings have the physical traits that enable them to use this feeding technique, which has undoubtedly helped the species spread far and wide.
In Iberia, the western Mediterranean and northwest Africa, the common starling may be confused with the closely related spotless starling, the plumage of which, as its name implies, has a more uniform colour. At close range it can be seen that the latter has longer throat feathers, a fact particularly noticeable when it sings.
The common starling is a noisy bird. Its song consists of a wide variety of both melodic and mechanical-sounding noises as part of a ritual succession of sounds. The male is the main songster and engages in bouts of song lasting for a minute or more. Each of these typically includes four varieties of song type, which follow each other in a regular order without pause. The bout starts with a series of pure-tone whistles and these are followed by the main part of the song, a number of variable sequences that often incorporate snatches of song mimicked from other species of bird and various naturally occurring or man-made noises. The structure and simplicity of the sound mimicked is of greater importance than the frequency with which it occurs. Each sound clip is repeated several times before the bird moves on to the next. After this variable section comes a number of types of repeated clicks followed by a final burst of high-frequency song, again formed of several types. Each bird has its own repertoire with more proficient birds having a range of up to 35 variable song types and as many as 14 types of clicks.

Was slightly amused by the 35 degree angle parking. Not sure I've come across that previously, and I wondered if a fine would be issued for non-compliance with the stated angle.
A couple of vehicles parked along here during my time in town, and they both parked parallel to the kerb. Not a parking inspector in sight !!
A triangle square, commonly known by the brand name Speed Square but also called a rafter (or rafter angle) square. This compact tool, in the form of an isoceles right triangle, was invented in 1925 as a framing tool; it is also useful for other materials like metals and plastic using its measurement and squaring features alone.
... I tried to take this photo straight on but the wind blew on me ... lol
no wonder that Chicago is called "The Windy City" ...
please .. don't use a protractor ... just turn your head a little :)
Repost of recent but not new abstract composition in Amity Street series where I started these with ballpoint pens, rulers, templates, protractors and salad bowls.

Had bugger all for shot of the day - and then I noticed my daughter’s protractor on the dining table. Done and dusted.

protractor / Winkelmesser
A protractor is a measuring instrument, typically made of transparent plastic or glass, for measuring angles. Most protractors measure angles in degrees (°). Radian-scale protractors measure angles in radians. Most protractors are divided into 180 equal parts.
They are used for a variety of mechanical and engineering-related applications, but perhaps the most common use is in geometry lessons in schools.
Some protractors are simple half-discs. More advanced protractors, such as the bebel protractor, have one or two swinging arms, which can be used to help measure the angle.
