It turns out that it is possible to make up an icosahedron using groups of more simple solids. One of such solids is a polyhedron in the shape of a tetrahedron!
In our case, three inner faces of the polyhedron should be slightly lower than those of the regular tetrahedron, as you can see in the figure. A regular triangle remains based on the polyhedron.
Combining these 20 “tetrahedra”, we get an icosahedron.
Just imagine how 20 totally identical polyhedra meet at a single point and make up a completely new polyhedron – icosahedron!
The following video, made by our partners, the team of “ART KOSEKOMA”, shows this transformation.
