public class Rectangle
extends Parallelogram
Creates an object representing a rectangle. The rectangle is determined by four points (p1, p2, p3, p4). p1 is assumed to be the upper left hand corner and the other points are assumed to be listed in clockwise order. For simplicity, the top and bottom with end points (p1,p2) and (p3,p4) of the parallelogram are assumed to be horizontal and the sides are assumed vertical.
