Even simple tessellations have many patterns that catch the eye. (If you have pictures of these available, your group may wish to look atĪre fascinating even just to look at. Tessellations can be as simple as these two examples, or as complex as a Tessellations that can be found every day are square tiles that cover a floorĪnd rectangular bricks that make walls. Tessellations, or tilings, are patterns of polygon shapes thatĬompletely cover a plane surface without overlapping and without leaving any Other cool links on Tesselations Totally Tessellated! – created by 3 HS seniors Cool Student made Tessellations Note: Pictures in this presentation found online.Introduction to Tessellations - Cooperative Activityīegin a short unit on tessellations. Glide reflections: the figure that results after reflection and translation. Rotations: the original shape is rotated around a central point. Reflections: a mirror image that is made of the original shape. Transformations Translations: when a shape is moved in any direction. Transformations are techniques used to take a shape and match it exactly to another. How are Tesselations made? Tessellations are made through a group of techniques called transformations. A demi-regular tessellation is a pattern of regular polygons in which there are two or three different polygon arrangements.this pattern can be folded to give unit cells of 2, 4, 6, or 8 squares per cell, and if wrapped around a cylinder, the pattern describes the way in which an overloaded cylinder buckles as it collapses.tessellation has 3 triangles and two squares at each vertex,.The vertex arrangement is the same throughout the entire pattern.A semi-regular tessellation is a pattern consisting of more than one type of regular polygon.A regular polygon is any many sided shape that has sides of equal length and angles or equalmeasure.A regular tessellation is a pattern only using one regular polygon shape.There are only three regular tessellations one of triangles one of squares and one of hexagons ![]() Examples: tessellation of squares- 4-4-4-4 tessellation of hexagons- 6-6-6Ī famous mathematician, Kepler studied tessellations and noted the regular tessellations or (tilings) of the plane. The convention number represents the number of sides of each polygon. Conventions are named based on the type of polygons that touch the vertex point. Naming a Tessellation A tessellation is named by looking at a vertex point and finding how many polygons touch the vertex point. Hydrogen Peroxide, among other chemicals, has this tessellating, crystal structure.īasic Types of Tesselations Three main types of tessellations: * Regular * Semi-Regular * Demi-Regular This image suggests the relationship between tessellations, symmetry, and x-ray crystallograpy This picture depicts the transformation of eight points in an array to make a very small crystal lattice, which tessellates.One example of such an array of columns is the Giant's Causeway in Ireland. The extensive crack networks that develop often produce hexagonal columns of lava. Basalticlava flows often display columnarjointing as a result of contraction forces causing cracks as the lava cools.These rectangular bricks are connected in a tessellation, which if considered an edge-to-edge tiling, topologically identical to a hexagonal tiling, with each hexagon flattened into a rectangle with the long edges divided into two edges by the neighboring bricks.He died at the age of 73 in March of 1972.Ī tessellation of a disk used to solve a finite element problem.-differential equations.Escher drew his last tessellation in July of 1969.He created his most famous tessellation, “Reptiles” in 1943.He began studying tilings around 1935.Born Jin the Dutch province of Friesland.Tessellations in Nature Snake skin spider Armadillo armor Tessellations in Architecture Islamic Arch Islamic MinaretĮveryday Tessellations!
