There are infinitely many non-similar shapes of icosahedra, some of them being more symmetrical than others. The best known is the ( convex , non- stellated ) regular icosahedron —one of the Platonic solids —whose faces are 20 equilateral triangles .
5 Platonic solids: 4 Kepler–Poinsot solids: 3 tilings: ... For example, in a polyhedron (3-dimensional polytope), a face is a facet, an edge is a ridge, ...
The 5 Platonic solids are called a tetrahedron, hexahedron, octahedron, dodecahedron and icosahedron with 4, 6, 8, 12, and 20 sides respectively. The regular hexahedron is a cube . Table of polyhedra
