A square pyramid has eight edges. Four of the edges are located where the faces meet each other to form the four sides, and the remaining four occur where the side faces meet the base.
Square pyramids have five faces. The four side faces are triangles, while the side that forms the base is a square. They also have five vertices — the four corner points of the base and the point at the top. Pyramids are named after the shape of the base. For example, a pyramid with a triangular base is called a "triangular pyramid." The Great Pyramids of Egypt are an example of famous square pyramids.
