Presentation Transcript
1. What is a Tessellation?

2. What is a Tessellation? • The graphic artist M.C. Escher (1898 – 1972) was intrigued with the idea of creating a single shape that could be copied and then used to cover a surface without any gaps or overlaps. • These coverings or tilings of the plane are called TESSELLATIONS.
