![]() ![]() ![]() The most famous pair of such tiles are the dart and the kite.Ĭlick here for the lesson plan of non-periodic Tessellations. The pattern of shapes still goes infinitely in all directions, but the design never looks exactly the same. ![]() In the 1970s, the British mathematician and physicist Roger Penrose discovered non-periodic tessellations. Whatever direction you go, they will look the same everywhere. They consist of one pattern that is repeated again and again. It may be better to show a counter-example here to explain the monohedral tessellations.Īll the tessellations mentioned up to this point are Periodic tessellations. Squares (or rectangles) Hexagons Equilateral Triangles. All regular tessellations are also monohedral. Escher featured tessellated patterns in many of his most famous works. If you use only congruent shapes to make a tessellation, then it is called Monohedral Tessellation no matter the shape is. Tessellations of a plane can be found in the regular patterns of tiles in a bathroom floor, or flagstones in a patio. The regular hexagon is mainly used in the pattern of a honeycomb. You can use Polypad to have a closer look to these 15 irregular pentagons and create tessellations with them. There are only three regular shapes that can even make up a regular tessellation: the equilateral triangle, the square and the regular hexagon. Among the irregular pentagons, it is proven that only 15 of them can tesselate. We can use any polygon, any shape, or any figure like the famous artist and mathematician Escher to create Irregular tessellationsĪmong the irregular polygons, we know that all triangle and quadrilateral types can tessellate. The good news is, we do not need to use regular polygons all the time. If one is allowed to use more than one type of regular polygons to create a tiling, then it is called semi-regular tessellation.Ĭlick here for the lesson plan of Semi - Regular Tessellations. If you try regular polygons, you ll see that only equilateral triangles, squares, and regular hexagons can create regular tessellations.Ĭlick here for the lesson plan of Regular Tessellations. the most well-known ones are regular tessellations which made up of only one regular polygon. There are several types of tessellations. ![]()
