A polyhedron with a polygon base and triangular sides that all meet at a common vertex is called a pyramid. The base can be any polygon (such as a triangle, square, or pentagon), and the triangular faces connect each edge of the base to the apex or common vertex at the top. Pyramids are named based on the shape of their base; for example, a pyramid with a square base is called a square pyramid.

A polyhedron with a polygon base and triangular sides that all meet at a common vertex is known as a pyramid. The base can be any polygon, such as a triangle, square, or pentagon, and the triangular sides are called lateral faces. The vertex where all the triangular faces converge is referred to as the apex of the pyramid. Each type of pyramid is named based on the shape of its base, such as a triangular pyramid or a square pyramid.

A regular pyramid has a regular polygon base and a vertex over the center of the base. By:Cherrylvr :)
A pyramid has a polygonal base with all other sides being triangles. As the Egyptians famously demonstrated, a common pyramid has a square base with four triangles meeting at a vertex, but any polygon - regular or irregular - can be used as the base of such a polyhedron.

A shape with a circular base and a vertex that isn't in the same plane as the base is called a cone.
