A pyramid is just a cone with a square base.
A cone is just a pyramid whose base has infinite sides
No, a cone can have any flat shape as its base, wherefor a pyramid - which only has four sides - is also a cone.
By definition, a pyramid can have any polygon as a base, not just a square. A cone can ONLY have a circle as a base.
I say Pyramids ⊂ Cones. You say Cones ⊂ Pyramids. Therefore Cones = Pyramids.
