![]() Tessellations form a class of patterns in nature, for example in the arrays of hexagonal cells found in honeycombs. Tessellations are sometimes employed for decorative effect in quilting. Escher often made use of tessellations for artistic effect. Historically, tessellations were used in Ancient Rome and in Islamic art such as in the decorative tiling of the Alhambra palace. Such tilings may be decorative patterns, or may have functions such as providing durable and water-resistant pavement, floor or wall coverings. In the real world, a tessellation is a tiling made of physical materials such as cemented ceramic squares or hexagons. In computer graphics, the term "tessellation" is used to describe the organization of information needed to render to give the appearance of the surfaces of realistic three-dimensional objects. The patterns formed by periodic tilings can be categorized into 17 wallpaper groups. Some special kinds of tessellations include regular, with tiles all of the same shape semi-regular, with tiles of more than one shape and aperiodic tilings, which use tiles that cannot form a repeating pattern. ![]() In mathematics, tessellations can be generalized to higher dimensions. Tessellations form a class of patterns in nature, for example in the arrays of hexagonal cells found in honeycombs.įreebase Rate this definition: 0.0 / 0 votesĪ Tessellation is the tiling of a plane using one or more geometric shapes, called tiles, with no overlaps and no gaps. Escher often made use of tessellations, both in ordinary Euclidean geometry and in hyperbolic geometry, for artistic effect. Historically, tessellations were used in Ancient Rome and in Islamic art such as in the Moroccan architecture and decorative geometric tiling of the Alhambra palace. ![]() A tessellation of space, also known as a space filling or honeycomb, can be defined in the geometry of higher dimensions.Ī real physical tessellation is a tiling made of materials such as cemented ceramic squares or hexagons. An aperiodic tiling uses a small set of tile shapes that cannot form a repeating pattern. A tiling that lacks a repeating pattern is called "non-periodic". All true tessellations fall under one of two categories: regular, and semi-regular. No more than 3 regular tessellations are possible because the sums of the interior angles are either greater or less than 360 degrees. Tessellations are geometrical patterns that can be fit perfectly together and be repeated indefinitely. There are only 3 which include triangle, square,hexagon. Some special kinds include regular tilings with regular polygonal tiles all of the same shape, and semiregular tilings with regular tiles of more than one shape and with every corner identically arranged. A regular tessellation is a pattern repeating a regular polygon. In mathematics, tessellation can be generalized to higher dimensions and a variety of geometries.Ī periodic tiling has a repeating pattern. See this article for more on the notation introduced in the problem, of listing the polygons which meet at each point.Wikipedia Rate this definition: 0.0 / 0 votesĪ tessellation or tiling is the covering of a surface, often a plane, using one or more geometric shapes, called tiles, with no overlaps and no gaps. Hexagons & Triangles (but a different pattern) Triangles & Squares (but a different pattern) We know each is correct because again, the internal angle of these shapes add up to 360.įor example, for triangles and squares, 60 $\times$ 3 + 90 $\times$ 2 = 360. There are 8 semi-regular tessellations in total. ![]() We can prove that a triangle will fit in the pattern because 360 - (90 + 60 + 90 + 60) = 60 which is the internal angle for an equilateral triangle. Students from Cowbridge Comprehensive School in Wales used this spreadsheet to convince themselves that only 3 polygons can make regular tesselations. For example, we can make a regular tessellation with triangles because 60 x 6 = 360. ![]() This is because the angles have to be added up to 360 so it does not leave any gaps. To make a regular tessellation, the internal angle of the polygon has to be a diviser of 360. Put what youve learned to the test with the activity below. Can Goeun be sure to have found them all?įirstly, there are only three regular tessellations which are triangles, squares, and hexagons. Tessellation that uses two shapes like this is called irregular tessellation, but a lovely tessellation nevertheless Nice one Activity. Goeun from Bangok Patana School in Thailand sent in this solution, which includes 8 semi-regular tesselations. ![]()
