![]() A square has an interior angle of 90°, so 4 squares fit together to make 360°: 360 ÷ 90 4. Muslim structure suggests evidence of tessellations and an example of this is the Alhambra Palace at Granada, inside the south of Spain. It is tempting to assume that each of the 17 regular wallpaper patterns gives rise to precisely one schema of regular tiling. Wallpaper patterns appear on wallpaper indeed, in brickwork, in oor tessellations, and so on. When you have finished, try answering the multiple-choice test. Regular polygons tessellate if the interior angles can be added together to make 360°. in essence there exist precisely seventeen distinct regular wallpaper patterns 7. Whay don't you try creating your own tessellation? You may need a pair of compasses, a ruler, a rubber, pencil, sellotape and some colour pencils. Now, have a look at this short video where you can learn how to create your own tessellation. Escher whose visits to La Alhambra inspired his work. La Alhambra in Granada (Spain) is a beautiful illustration of that.Īnd another reference of this artistic expression is the Dutch artist M.C. Can you name the type of tessellation of each example?īut maybe one of the most interesting examples of tessellation is the decoration of walls in the Islamic architecture. Can you think of some?Ī brick wall, a honeycomb or a pavement are simple examples of tessellations in everyday life. ![]() We live surrounded by things that are tessellated. All triangles and quadrilaterals will tessellate. These are tessellations with nonregular simple convex or concave polygons. There is an infinite number of such tessellations. ![]() Now let's focus on this geometric art in real life Non-regular tessellations is a tessellation in which there is no restriction on the order of the polygons around vertices. There are lots of different tessellations. Other more complex tessellations can be made of irregular polygons or other shapes such as circles, animals, etc. For the figures above, is the pattern the same at each vertex? In the second example there are triangles and dodecagons. In the first example we can see a combination of octogons and squares. ![]() So now you do not see the same figure repeated all the time but a combination of two or more. To name a tessellation you have to count how many sides each polygon has and also look at the corner point of each figure -the vertex- and count the number of figures that meet there.Īre made of two or more regular polygons. Squares Hexagons and Equilateral triangles A Tessellation or Tiling is the process of covering a surface with a pattern of flat shapes so that there are no gaps or overlaps.Īre those made of the repetition of these three regular polygons: ![]()
