- A helix is a type of smooth space curve, i.e. a curve in three-dimensional space. It has the property that the tangent line at any point makes a constant angle with a fixed line called the axis. Examples of helices are coil springs and the handrails of spiral staircases.

 

- A "filled-in" helix (for example, a "spiral" (helical) ramp) is called a helicoid.
