Class Name: Polygon

Superclass - Surface Geometry

Definition

A bounded portion of a plane, defined by a set of three or more Vertices listed in counter-clockwise order. The final segment connecting the last Vertex to the first Vertex is implicit, not explicit. (The first Vertex is not duplicated to also appear as the last Vertex of the Polygon).
