star

Star polygons and polygonal compounds are the basis for numerous figures of significance in arts and culture. The figure may be the border or interior of the polygon, or one or more closed polygonal paths that include all of the border and also have some legs crossing the interior. The name is derived from the polygon's similarity to the diffraction spikes of astronomical stars, but specific uses may exploit the connection or not. Stars often represent the unity of states within a country when they are used as a part of the flag.
