Arrangement of geometric shapes on a plane surface or region without any gaps or overlapping between the shapes.
The arrangement of shapes in three-dimensional space is called a honeycomb.
Property
Of the regular polygons, only equilateral triangles, squares, hexagons, octagons and decagons can be used to create a tessellation on a plane, and in 15 different arrangements.
Examples
This is an example of a periodic tessellation using squares and rectangles:
This tessellation is obtained through rotations and reflections of the same pattern :
This tessellation is made up of regular hexagons only:
