Truncated tetrahedron

Truncated tetrahedron

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

A truncated tetrahedron is a semi-regular 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.

Архимед

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 while the condition of one of the types of spatial symmetry (tetrahedral, octahedral or icosahedral) is preserved.

Video. The process of converting a tetrahedron to a truncated tetrahedron

Truncating all four vertices of the tetrahedron leads to the formation of a truncated tetrahedron. The triangular faces of the original polyhedron lose their area and are converted to hexagonal faces.

This video from our partners, the ART KOSEKOMA team, clearly demonstrates how the pattern is converted into a geometric shape:

Truncated tetrahedron from the set "Magic Edges"

To assemble polyhedra, we can offer you ready-made patterns that are cut and folded.
To do this, you need to use the details of the set Magic Edges 18.
In addition, in the release itself you will find information about the structure of the polyhedron.
