Are all pyramids platonic solids?

No, because the base of the triangle can be basically any polygon, and only a triangle with an equilateral triangle is a platonic solid.

Any triangular pyramid is a tetrahedron, but not necessarily a regular tetrahedron. The pyramids in Egypt and Central America are square pyramids, by the way, not triangular.
