# 2D Puzzles generated using a tessellation of the plane

Many 2D Puzzles are generated using a tessellation of the plane.

The word "tessellate" means to form or arrange polygons in a checkered or mosaic pattern. It is derived from the Ionic version of the Greek word "tesseres", which in English means "four". The first tilings were made from square tiles.

A regular tessellation means a tessellation made up of identical regular polygons. Only three regular polygons completely tessellate (cover) the Euclidean plane: triangles, squares and hexagons.

A semiregular tessellation uses a variety of regular polygons. The arrangement of polygons at every vertex point is identical.

In tessellations (tilings) of the plane, mathematical methods can be often applied in helping to derive solutions. This collection of puzzles demonstrates this is not always true.

To solve the puzzles the pieces must fill the entire area of the given game board.

This might be difficult sometimes :-)
