The ancient Greeks gave the polyhedron a name according to the number of faces. “Dodeca” means twelve, “hedra” means a face (a dodecahedron is a solid with twelve faces).

The polyhedron belongs to regular polyhedra and is one of the five Platonic solids.

The dodecahedron has the following characteristics:

Face type - regular pentagon;

The number of sides at the verge is 5;

The total number of faces is 12;

The number of edges adjacent to the top is 3;

The total number of vertices is 20;

The total number of edges is 30.

The regular dodecahedron is composed of twelve regular pentagons. Each vertex of the dodecahedron is the vertex of three regular pentagons. Therefore, the sum of flat angles at each vertex is 324 °.

The dodecahedron has a symmetry center - the center of the dodecahedron, 15 axes of symmetry, and 15 planes of symmetry.
