STAR: A GEOMETRIC SHAPE
By geometrical definition, a star is a regular polygon: simple or complex.
Remember...
Polygon - any two-dimensional shape formed with straight lines and is closed.
REGULAR POLYGON - a polygon whose sides are all the same length (equilateral)
and whose angles are all the same (equiangular).
A SIMPLE POLYGON - an enclosed shape consisting of straight, non-intersecting
lines.
A COMPLEX POLYGON - an enclosed shape consisting of straight lines that
intersect.
A CONVEX POLYGON - defined as a polygon with all its interior angles less than
180°; otherwise, the polygon is CONCAVE.
STAR POLYGONS
A "regular star polygon" is therefore, a self-intersecting, equilateral
equiangular polygon. A regular star polygon is denoted by its Schläfli symbol
{p/q}, where p = the amount of vertices / sides and q = the adjointment interval..
