A regular star polygon is constructed by joining nonconsecutive vertices of regular convex polygons of continuous form.

They are denoted by **p/q**, where **p** is the number of vertices of the convex regular polygon and **q** is the jump between vertices.

p/q must be an irreducible fraction (in reduced form).

The polygon p/q is the same as the p/(p − q), as the polygon is obtained by joining vertices in a counterclockwise direction.
