WebJan 4, 2024 · An octagonal pyramid has nine vertices; eight are located where the triangular faces meet the base and the ninth is the point at which all of the triangular faces meet at the top of the pyramid. In geometry, a pentagonal pyramid is a pyramid with a pentagonal base upon which are erected five triangular faces that meet at a point (the apex). Like any pyramid, it is self-dual. The regular pentagonal pyramid has a base that is a regular pentagon and lateral faces that are equilateral triangles. It is one of the Johnson solids (J2).
