![]() ![]() You’ll soon find out which shapes don’t tile. This is a fun way to learn new maths concepts. Once you start getting the hang of this without the underlying maths, you can start trying other tilings. Try different shapes to practise. Now you’re tiling! As long as your geometric shape doesn’t overlap, you’re fine. Try to find all the types of symmetry available. Now you have your starting point, you’re going to place it on the other sheet, trace around it, and repeat. To try it out for yourself, get two pieces of paper, coloured pencils or felt tips, and some scissors. Choose your geometric shape and cut it out of the paper (you won’t need much mathematical knowledge to do this) and anyone can do this exercise. Before you can tile effectively, you need to understand the maths behind it. ![]() Learn how to calculate the median How to TileĪs you’ll have understood, this is used in art, architecture, nature, and not just maths lessons. “We often hear that mathematics consists mainly of 'proving theorems.' Is a writer's job mainly that of 'writing sentences?” - Gian Carlo Rota Now you know how tilling works, you can start tiling for yourself. We can also talk about periodic tiling (tessellation) with quadrilaterals and there’s also the idea of tiling in 3-dimensional space, too. Some patterns occur with symmetry and isometry and are known as wallpaper groups. Isometry is a congruent transformation across a plane. Isometry is when the points of a shape through translation, rotation, or symmetry are moved to a new place but are still the same distance apart. We can talk about isometry when certain tiles or pavings are identical. Semiregular tilings can be one of eight possible combinations. Of course, you can still get quite creative with these combinations. For example, an equilateral triangle, square, or hexagon can be used. You can classify different types of tiling. Euclidean tilings by convex regular polygons are when a single shape can tessellate without leaving a gap. In crystallography (the science looking at crystalline structures at the atomic scale), tiling and tessellation also occur. Typically, when we refer to tessellation and tiling, we’re talking about Euclidean geometry.Ī lot of shapes including squares, rectangles, hexagons, parallelograms, pentagons, and triangles can be used to create tessellations and the polygons don't even have to be regular to tessellate, though you'll probably find a regular polygon easier to create a pattern with. Tessellation in maths is covering a plane with one or several different geometric shapes. Much like tiling in the real world, tiling in mathematics is about covering a surface. Whether it’s tiled or paved streets, the tiling in your bathroom, or stained-glass windows in a church, there are plenty of examples of geometric shapes and polygons in a pattern that tiles a plane. When you have finished, try answering the multiple-choice test.You probably see tiling and tessellations regularly in your everyday life. 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. Now let's focus on this geometric art in real life 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: ![]()
