No, a dodecahedron is a 3-dimensional shape. Some of the 6.4 million topologically distinct dodecahedra have only triangulat faces, there are many more in which some faces, but not all, are triangular.

There are 5. They are the tetrahedron (4 triangular faces), the cube (6 square faces), the octahedron (8 triangular faces), the dodecahedron (12 pentagonal faces), and the icosahedron (20 triangular faces).

A dodecahedron is a polyhedron with twelve faces. It comes from the Greek words dodeka, meaning twelve, and hedra, meaning face.

I assume you mean a regular dodecahedron. A regular dodecahedron has twelve faces, each of which are regular* pentagons. *(all sides are congruent, all angles are congruent)

Five sides.

a triangular pyramid is a triangular prism but it doesn't work vise-versa. The prism needs a minimum of 1 triangle face but it can have more.A pyramid can only have one triangular face.

The solid shape that has one square face and four triangular faces is called a pyramid. If you were to have a shape that had four triangular faces and no square face, it would be called a triangular pyramid.

20 faceted (regular) polyhedron is a icosahedron - all facets have equal size. There are variations which have more specific names (where certain facets have irregular shapes) An interesting site to look at is polyhedra.org which shows 6 other variations of 20 faceted polyhedrons: 1. gyroelongated triangular cupola 2. parabiaugmented dodecahedron 3. metabiaugmented dodecahedron 4.triangular hebesphenorotunda 5.gyroelongated triangular cupola 6. elongated triangular orthobicupola
