An n-sided pyramid is a polyhedron formed by connecting an n-sided polygonal base and a point, called the apex, by n triangular faces (nâ¥3). In other words, it is a conic solid with polygonal base.
When unspecified the base is usually assumed to be square. For a triangular pyramid each face can serve as base, with the opposite vertex as apex. One of the Platonic solids, the tetrahedron, is a triangular pyramid. The square and pentagonal pyramids can also be constructed with all faces regular, and so count among the Johnson solids. All pyramids are self-dual.
Pyramids are a subclass of the prismatoids.

There is a book titled "The Great Pyramid Decoded", by Captain. I hope I spelled his name correctly. I found the book very interesting and informative. I hope you do the same.
