Triangular Pyramid
A one stop resource

When people think of a triangular pyramid, most will automatically think of it as a type of Platonic Solid - the Tetrahedon. So I feel I must clarify this first.

Every tetrahedron is a triangular pyramid, but every triangular pyramid is NOT a tetrahedron. It is only a Platonic Solid if all it's faces are congruent, regular polygons, in this case

if every triangle is equilateral and equal in size.
