First off, don't make any changes to the "Polygon" class. When you create "Square", it should be a new class. It will be in the same namespace but it will not be inside "Polygon".

You'll need to reference the base class in both the declaration and the constructor. You might want to take another look at the first two videos of this stage because you can see examples of how this is done there.
