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.
