circle :: (TrailLike t, (~) (* -> *) (V t) V2, (~) * (N t) n, Transformable t) => n -> t

A circle of the given radius, centered at the origin. As a path, it begins at (r,0).

square :: (InSpace V2 n t, TrailLike t) => n -> t

A square with its center at the origin and sides of the given length, oriented parallel to the axes.

triangle :: (InSpace V2 n t, TrailLike t) => n -> t

An equilateral triangle, with sides of the given length and base parallel to the x-axis.
