# Divide the icosahedron (into parts)

Is it possible to make up an icosahedron using more simple polyhedra?

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!
