1) Consider a graphics system that has classes for various figures, say rectangles, squares, triangles, circles and so on.  For example, a rectangle might have data members height, width, and center point, while a square and circle might have only a center point and an edge length or radius respectively.  In a well designed system these would be derived from a common class, Figure.  For this assignment, you are required to implement such a system.
