public class Trapezoid
extends Quadrilateral
The class Trapezoid defines a trapezoid object. For simplicity, the two parallel sides of the trapezoid are assumed to be horizontal. The trapezoid 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.
