If you want to see the applet work, visit Sun's website at, download and install Java VM and enjoy the applet. This applet requires Sun's Java VM 2 which your browser may perceive as a popup. A turtle shell shows a special tessellation (at least for Kristian) since they use multiple, different shapes, instead of seeing the same shape over and over. This is a hexagon, but it is not quite regular, so we only know that the interior angles add up to 720 degrees. For example, a less regular tessellation is obtained when the rhombi are free to become parallelograms. The snake skin is also a perfect example of a tessellation. Tessellations form a class of patterns in nature, for example in the arrays of hexagonal cells found in honeycombs. It is possible to further relax the original constraints. As a result, it is easily morphs into a derivative of a 4, 4, 4, 4 tessellation. The one below lets loose the equilateral triangles. Each example provides the notation and AB edge in radians as well as. A structure that is created by repeatedly using a regular polygon is referred to as a normal tessellation. These come in various combinations, such as triangles & squares, and hexagons & triangles. These are known as semi-regular tessellations. As previously mentioned, a tessellation pattern doesn’t have to contain all of the same shapes. An alternative name for a tessellation is a tiling. Accordingly, there are two implementations. Table 3 provides a range of examples of quasi-regular tessellations based on chained triangles as described in this paper. An example of a hexagonal tessellation pattern that you’ll find in day-to-day life is a honeycomb. A tessellation is created when one or more shapes are used to completely cover a plane, with no gaps or overlaps. We may only preserve either the squares or the equilateral triangles, but not both. Tessellations of the plane by two or more convex regular polygons such that the same polygons in the same order surround each polygon vertex are called semiregular tessellations, or sometimes Archimedean tessellations. There are two ways to set this tessellation on hinges. There are exactly three regular tessellations composed of regular polygons symmetrically tiling the plane. In particular this is what makes it semi-regular: a semi-regular tessellation combines more than one kind of regular polygons, but the same arrangement at every vertex. The tessellation itself is identified as (4, 3, 3, 4, 3) because 5 regular polygons meet at every vertex: a square, followed by two equilateral triangles, followed by a square and then again by an equilateral triangle. The applet implements a hinged realization of one semi-regular plane tessellations.
