Square isa Rectangle isa Polygon

Not quite. Square is both a Rectangle and a Rhombus, both of which are Parallelograms which isa Quadrilateral which isa Polygon. In addition, Square->is_regular_polygon() is true where none of the other classes mentioned in this listing can make that claim. is_regular_polygon() would be a method of Polygon.

My criteria for good software:
  1. Does it work?
  2. Can someone else come in, make a change, and be reasonably certain no bugs were introduced?
