Related to this topic is the work of the artist M.C. If you need a detailed description of that principles, push the button. We will discover in the following diagrams, how this design can be “mapped onto” itself, which is the fundamental idea of how tessellations work. There are basically 4 ways of how a diagram can be “mapped onto” itself, namely, by translation, rotation, reflection and glide reflection.
To illustrate the principals behind a simple tessellation pattern, a tiling consisting of equilateral triangles of degree 6 at each vertex is used as an example to illustrate these principles. There are certain principles of tessellations. There are exactly three regular tessellations composed of regular polygons symmetrically tiling the plane. Tessellations however, do not need the use of regular polygons, below is an example. By definition, tilings require the use of regular polygons put together such that it completely covers the plane without overlapping or leaving gaps. There is a difference between a tiling and a tessellation. In other words a tiling of regular polygons (in two dimensions), polyhedra (three dimensions), or polytopes (n dimensions) is called a tessellation. You can also use pieces of clay, bits of gummy candies, or other similar (sticky) material.What are tessellations? It is an arrangement of closed shapes that completely cover the plane without overlapping or leaving gaps. The best material for this is mini marshmallows you can stick the ends of the toothpicks into the marshmallows to connect them. You’ll also need something to connect the toothpicks together.Building Towersįor this activity, you will need some construction materials: If you want to try a more complicated version, cut two different squiggles out of two different sides, and move them both. Color in your basic shape to look like something - an animal? a flower? a colorful blob? Add color and design throughout the tessellation to transform it into your own Escher-like drawing.Ĩ.
The shape will still tessellate, so go ahead and fill up your paper.ħ. Then move it the same way you moved the squiggle (translate or rotate) so that the squiggle fits in exactly where you cut it out.Ħ. On a large piece of paper, trace around your tile. It’s important that the cut-out lines up along the new edge in the same place that it appeared on its original edge.ĥ. You can either translate it straight across or rotate it.Ĥ. Cut out the squiggle, and move it to another side of your shape. Draw a “squiggle” on one side of your basic tile.ģ. The first time you do this, it’s easiest to start with a simple shape that you know will tessellate, like an equilateral triangle, a square, or a regular hexagon.Ģ. Here’s how you can create your own Escher-like drawings.ġ. Work on the following exercises on your own or with a partner. Explain why regular pentagons will not tessellate.Use angles to explain why regular hexagons will tessellate.
Can you fit the squares together in a pattern that could be continued forever, with no gaps and no overlaps? Can you do it in more than one way? In each problem, focus on just a single tile for making your tessellation. You will need lots of copies (maybe 10–15 each) of each shape below. Work on these exercises on your own or with a partner. Tessellations are often called tilings, and that’s what you should think about: If I had tiles made in this shape, could I use them to tile my kitchen floor? Or would it be impossible? On Your Own The first two tessellations above were made with a single geometric shape (called a tile) designed so that they can fit together without gaps or overlaps.

So we’ll focus on how to make symmetric tessellations. It’s actually much harder to come up with these “aperiodic” tessellations than to come up with ones that have translational symmetry. The Penrose tiling shown below does not have any translational symmetry. Many tessellations have translational symmetry, but it’s not strictly necessary. The idea is that the design could be continued infinitely far to cover the whole plane (though of course we can only draw a small portion of it). Geometry in Art and Science TessellationsĪ tessellation is a design using one ore more geometric shapes with no overlaps and no gaps.
