Truncated tetrahedron. How to make pdf template

Truncated tetrahedron

This polyhedron is obtained by successively cutting off each of the vertices of the tetrahedron.

A truncated tetrahedron is a semiregular convex polyhedron with two properties:
1. All faces are regular polygons of two types, a hexagon, and a triangle;
2. For any pair of vertices, there is a symmetry of the polyhedron (that is, a motion that translates the polyhedron into itself) that transforms one vertex to another.

Archimedes

The truncated tetrahedron is one of the 13 solids of Archimedes.

Archimedean solids are semiregular polyhedra in the sense that their faces are regular non-similar polygons. Simultaneously, the condition of one of the types of spatial symmetry (tetrahedral, octahedral, or icosahedral) is preserved.
