The polygons are the equilateral triangle, the square, and the regular pentagon. The faces of these platonic solids are made from the following polygons: tetrahedron - 4 triangles cube - 6 squares octahedron - 8 triangles dodecahedron - 12 pentagons icosahedron - 20 triangles
triangles, squares and pentagons.
You can actually learn to make an origami one. But its a 12 sided figure with each face having 5 sides in my past experience. A dodecagon is a 12-sided polygon, a 2-dimensional figure. The dodecahedron is a 12-sided polyhedron, a 3-dimensional object of 12 pentagonal faces and 20 vertices. The dodecahedron is also one of the Platonic solids. * * * * * The above is a totally confused answer. It conflates a a dodecagon and a dodecahedron. The first, which the question is about, is a plane (2-D) figure which is bounded by 12 straight lines. The second, which has nothing to do with the question, is a solid (3-D) shape enclosed by 12 pentagonal faces.
A four-faced solid is called a tetrahedron.

dodecahedron
A dodecahedron. A dodecahedron is any polyhedron with twelve faces, but usually a regular dodecahedron is meant. It is a Platonic solid composed of twelve regular pentagonal faces, with three meeting at each vertex. It has twenty (20) vertexes and thirty (30) edges. The dodecahedron would be the Platonic solid with the largest volume if all were made with edges of the same length.
Dodecahedron
The Platonic Solids: Tetrahedron, cube, octahedron, dodecahedron and icosahedron.
A Platonic solid is a solid all of whose face are regular and congruent polygons.There are five of these:A Tetrahedron. Four faces, each an equilateral triangle.Ad InfoA Hexahedron (Cube). Six faces, each a square.An Octahedron. Eight faces, each an equilateral triangle.A Dodecahedron. Twelve faces, each a regular pentagon.An Icosahedron. Twenty faces, each an equilateral triangle.

Tetrahedron (4 faces), Cube (6), Octahedron (8), Dodecahedron (12) and Icosahedron (20).
A trapezoid is not a platonic solid. There are only five platonic solids. They are the tetrahedron, hexahedron, octahedron, dodecahedron, and icosahedron.
No, a cone is not a Platonic solid. The Platonic solids are the five regular polyhedra: tetrahedron, cube, octahedron, dodecahedron, and icosahedron.
They all are, with 6, 20, 8, 4 and 12 faces respectively.
No; platonic solids are tetrahedron, cube, octahedron, dodecahedron, icosahedron.
No; platonic solids are tetrahedron, cube, octahedron, dodecahedron, icosahedron.
