How Many Edges Does a Pyramid Have?
A Cheops or square pyramid has eight edges. This type of pyramid also has five faces, including the base, as well as five corners, known as vertices. This is the type of design used in the construction of the Great Pyramids in Egypt.
In addition to the traditional Cheops or square pyramid, there exists what is known as a triangular pyramid. A triangular pyramid has only six edges. In addition, this type of pyramid has four faces and four vertices. Other types of pyramids not commonly seen include a pentagonal pyramid, a hexagonal pyramid and a heptagonal pyramid. These more unusual types of pyramids are most often seen in educational and classroom settings.
