The materials are flexible enough to be used in almost any class from algebra and geometry through precalculus, and are ideal for discrete mathematics or college preservice classes. Each of these modules is available, free of charge, to COMAP members for use in the classroom. Photocopying is permitted for use only within a single class of students or teachers. The material may not be sold or modified in any way without written permission from COMAP. COMAP members can download and use any of these units: Graph Models , by Joseph Malkevitch Looking at the problems faced by delivery people, storeowners, coaches, airline operations managers, and more, your students learn how to analyze real situations using mathematical models. Shortest Paths Robots like SARAH, a robot that performs neurosurgical procedures, often use graph theory to make "decisions" about where to go. Students explore a variety of algorithms designed to calculate efficient routes and try to find their own optimal solutions.

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.

Uniform tessellation 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.

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:

Tilings and Tesselations In this article, you can read about many different kinds of tiling, the math behind them, how to make them, and classify them! You can also experiment interactively with tilings using Contents The Tilings Around Us What is a tiling? We are surrounded by familiar tilings every day, like brick walls and tile floors. Tiling Terminology To mathematicians and scientists, there are an infinite number of different kinds of tilings symmetric ones, ones made with one shape of tile, even completely random ones. Learn some of the mathematical terms and definitions about tilings Periodic Tilings Tilings naturally fall into two classes. Some have repeating patterns, and some don't. This page takes a closer look at repeating, or periodic tilings. Symmetric Tilings A floor covered with square tiles and a floor covered with hexagonal tiles both have regular, symmetric, repeating patterns, but they are clearly different. What is symmetry, and how do you measure it? Wallpaper Groups Wallpaper groups are sets of rules for building highly symmteric tilings froma single piece. Surprisingly, there are exactly 17 of them! See animations of these beautiful and intriguing tilings here. Non-Periodic Tilings Some tilings don't repeat. However, that doesn't mean that they a totally random. Some of the most fascinating tilings have an element of randomness mixed in with a basically regular pattern.

Here is a screen shot of the "Table of Contents" to show the scope of the CD. The Dutch artist M.C. Escher is famous for the animal forms that fit together without gaps. He is interested in the broad topic of space and geometry. Tiling with geometric patterns is around for several thousand years. It seems Escher has ignated an interest in people across different cultures. The following screen shot shows a portion of people following Escher's ideas and inspiration. Knowledge of MATH is not necessary to make beautiful tessellations. I found that people with art talents do the best. Many craftsmen made besutiful designs. In the CD, I showed how people

Tessellations 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
