    TRUNCATED ICOSAHEDRON An icosahedron is one of the five Platonic solids (tetrahedron, cube, octahedron, and dodecadhedron are the others). The 20 faces of the icosahedron are congruent equilateral triangles. If planes sliced the icosahedrons at the 1/3 point of each edge, each triangle would become a hexagon, and a pentagon would replace each vertex of the original icosahedron.

    The soccer ball and the ball used in the Olympic sport of team handball is an example of a spherical analog (rounded) of a truncated icosahedron. The flexibility of the surface of these balls and the air pressure on their contents results in this familiar round shape.
