“In short, a tessellation is any repeating pattern of interlocking shapes. Tessellations are also sometimes known as tilings, but the word ’tilings’ usually refers to patterns of polygons (i.e., shapes with straight boundaries), which is a more restrictive category of repeating patterns. The definition sounds fairly simple, but the ideas involved in designing and understanding tessellations can grow very complex and interesting. This site will give you a comprehensive introduction to tessellations. It will explain the basic mathematics underlying tessellations, as well as allow you to browse through many examples of tessellations in real life. M. C. Escher and his well-known tessellations are also covered in this site.”
