One may also speak of tessellations of parts of the plane or of other surfaces. Generalizations to higher dimensions are also possible. Tessellations frequently appeared in the art of M. C. Escher . Tessellations are seen throughout art history, from ancient architecture to modern art In Latin, tessella is a small cubical piece of clay stone or glass used to make mosaics The word "tessella" means "small square" (from " tessera ", square, which in its turn is from the Greek word for "four"). It corresponds with the everyday term tiling which refers to applications of tessellations, often made of glazed clay. Tilings with translational symmetry can be categorized by wallpaper group , of which 17 exist. All seventeen of these groups are represented in the

Extractions: From Wikipedia, the free encyclopedia Jump to: navigation search In geometry , a uniform tessellation is a vertex-transitive tessellations made from uniform polytope facets . All if its vertices are identical and there is the same combination and arrangement of faces at each vertex. An n-dimensional uniform tessellation can be constructed on the surface of n-spheres, in n-dimensional Euclidean space, and n-dimensional hyperbolic space. Nearly all uniform tessellations can be generated by a Wythoff construction , and represented by a Coxeter-Dynkin diagram . The terminology for the convex uniform polytopes used in uniform polyhedron uniform polychoron uniform polyteron uniform polypeton ... uniform tiling , and convex uniform honeycomb articles were coined by Norman Johnson Wythoffian tessellations can be defined by a vertex figure . For 2-dimensional tilings, they can be given by a vertex configuration listing the sequence of faces around every vertex. For example 4.4.4.4 represents a regular tessellation, a square tiling , with 4 squares around each vertex. In general an n-dimensional uniform tessellation vertex figures are define by an (n-1)-polytope with edges labeled with integers, representing the number of sides of the polygonal face at each edge radiating from the vertex.

Tessellations Fitting geometric shapes into each other to fill a plane surface is called tiling. A tessellation is the name given to a type of pattern made up of congruent shapes which interlock http://mathforum.org/~sanders/geometry/GP07Tessellations.html
Extractions: 7) Tessellations Fitting geometric shapes into each other to fill a plane surface is called tiling. A tessellation is the name given to a type of pattern made up of congruent shapes which interlock without overlapping or leaving any gaps. Which of the regular polygons can be used as the base unit of a tessellation? The question becomes, then, which ones will fit together to "fill the plane". This depends on their angles. Lets look at the regular polygons, one by one to see which ones will work in a tessellation. The interior angles of an equilateral triangle are each 60 degrees. If we put 6 equilateral triangles together, the three 60 degree angles add up to 360 degrees, and the triangles do "fit together perfectly: We already know that quadrilaterals, with their 90 degree angles, fit together perfectly. Five doesn't fit well, as 108 degrees doesn't divide evenly into 360. 360 degrees is perfectly divisible by 3, and the hexagon is one of the most common tiling patterns: tiles, fences, a patchwork quilt ...even those natural mathematicians, the honeybees, know what a perfect geometric figure the hexagon is. The exterior angles of a seven-sided figure are found by dividing 360 by 7, which is approximately 51.43 degrees, so the interior angles are approximately 128.57 degrees. A seven-sided polygon will not tile:

Geometry formally defines a tessellation as an arrangement of repeating shapes which leaves no spaces or overlaps between its pieces. There are usually no gaps or overlaps in patterns of octagons and squares; they "fit" perfectly together, much like pieces of a jigsaw puzzle. Not all shapes, however, can fit snugly together. Circles, for instance, would not create a tessellation by themselves, because any arrangement of circles would leave gaps or overlaps. Despite the limitations on the types of shapes that can form this intriguing pattern, there are many varieties of tessellations. Patterns using only one regular polygon to completely cover a surface are called regular tessellations . You can find examples of these on chess- or checkerboards. Semi-regular tessellations , on the other hand, use a combination of different regular polygons, such as the pattern above, and you can typically see examples of these patterns in the tilework of bathroom and kitchen floors. Tessellations made from regular polygons (equilateral triangles, squares, and hexagons) are usually referred to as
