Pyramids.

A pyramid is a polyhedron for which the base is a polygon and all lateral faces are triangles.

Technically, when the lateral faces are congruent triangles, the shape is known as a right pyramid, indicating that the apex — the vertex at which the lateral faces meet — is directly above the center of the base.
