An icosahedron is a polyhedron with 20 faces, each of which is an equilateral triangle. It has 12 vertices and 30 edges. The icosahedron is one of the five Platonic solids, which are the only convex polyhedra with faces that are all regular polygons of the same type and with the same number of faces meeting at each vertex.
