As you can see, Shape and Plotter act as base classes for all the others. Polygon inherits directly from them, RegularPolygon inherits from Polygon, and both RegularHexagon and Square inherit from RegulaPolygon. Note also that Shape and Plotter implicitly inherit from object, therefore we have what is called a diamond or, in simpler terms, more than one path to reach a base class. We'll see why this matters in a few moments. Let's translate it into some simple ...
