  1. Tesselations Where Art and Geometry Meet!

  2. What shapes can tile the plane? In other words, shape can you put next to itself and NOT have any gaps? Hexagons? Circles? Octagons? Triangles?

  3. Regular Tessellations When the shape used to tile the plane are the same regular polygons the tessellation is called regular. These are the only regular tessellations. Hexagons Triangles Squares

  4. American Quilters have been using simple shapes to tile the plane for hundreds of years. Sometimes they repeat the same shape and use color to create a pattern.

  5. Even the simplest of shapes, the triangle, can be used to create complex and beautiful patterns.

  6. Rectangles and squares can also be used to create interesting designs.

  7. Semi-Regular Tessellations If you vary the shapes you can still tile the plane. If the same group of regular polygons meet at every vertex, the tessellation is call Semi-Regular. There are only eight semi-regular tessellations. Can you name all eight semi-regular tessellations? Remember that the angles at each intersection must add up to 360. Use this chart to aid you in naming at least four of them.

  8. You name semi-regular tessellations by polygons (number of sides) going clockwise. Try to name the eight pictured tessellations. 4.8.8 3.3.3.3.6 3.12.12 3.4.6.4 3.3.4.3.4 4.6.12 3.3.3.4.4 3.6.3.6

  9. Beautiful, interesting patterns emerge when the different polygons are repeated across the plane. Even trompel’oeil!

  10. TrompeL’Oeil From the Past Medieval Italian Mosaics

  11. Storm at Sea

  12. The Fantabulous Worlds of Escher!

  13. Escher created this lithograph to demonstrate how his tessellations evolve. 2 through 4 are rhombi. In 5 he starts his metamorphosis. By 7 the birds are formed. In 8, 9, and 10 he adds detail. Magically, in 11 and 12 the birds become fish!
