Isosceles triangles can be used in domes
A pyramid is a generic term used to describe a polyhedron with a polygonal base and a number of triangles rising from that base to meet at an apex. A pyramid whose base is a polygon with n-sides (or vertices) has n+1 faces, n+1 vertices and 2n edges, where n >= 3.

The apex.
A square pyramid has a square base and four triangles attached to each of the square's edges which meet at a vertex (the apex) above the square.A cylinder had two parallel circular faces with a curved surface joining them.
A pyramid is a generic term used to describe a polyhedron with a polygonal base and a number of triangles rising from that base to meet at an apex. A pyramid whose base is a polygon with n-sides (or vertices) has n+1 faces, n+1 vertices (corners) and 2n edges, where n >= 3.
