An [equilateral] triangle, square and hexagon are the only regular polygons which, by themselves, will tile a surface.
Bone
Triangles, squares and hexagons. That is if they all have to be the same. If you use different regular polygons, you can tile a flat surface with triangles and 12-sides or with squares and 8-sides for example.
