Now let’s try to tessellate a floor using equilateral triangles. Each angle in a equilateral triangle is 60º . We see we can lay six identical equilateral triangles together, and they will complete the circle.

What about using squares, hexagons, octagons, or a combination? Here are some tessellations of planes.

In a similar way, space can be tessellated – tiled with three-dimensional solids. Pictured below are truncated octahedra. They are the only Archimedean polyhedra that can be used to fill space while leaving no gaps and using no other shaped solids.
