Icosahedron. How to make pdf template

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

Therefore, the question “What is an icosahedron?” The following definition can be given: “An icosahedron is a geometric solid of twenty faces, each of which is a right triangle.”


The polyhedron belongs to regular polyhedra and is one of the five Platonic solids.
The icosahedron has the following characteristics:

The face type is a regular triangle;
The number of sides at the verge 3;
The total number of faces is 20;
The number of edges adjacent to the top is 5;
The total number of vertices is 12;
The total number of edges is 30.


The regular icosahedron is composed of twenty equilateral triangles. Each vertex of an icosahedron is a vertex of five triangles. Therefore, each vertex's sum of flat angles is 300° (60° * 5).
The icosahedron has a center of symmetry - the center of the icosahedron has 15 axes of symmetry and 15 planes.
