2. Tesselations

3. What is a tesselation? It is a design consisting of the same interlocking pattern repeated over and over

4. M. C. Escher 1898 - 1972 Born in Holland Studied architecture Famous artist Mathematical ties Used symmetry and tesselations http://gonzo2236.tripod.com/escher.html

5. This is a sample of a tesselation using a geometric shape.

6. Regular Tesselation Rules: Must be a regular polygon Polygons cannot overlap or connect Each vertex must be the same Angles that form vertices must equal 360º

7. Is this a regular tesselation?

8. Why or why not?

9. Semi-regular Tesselations Rule: Must use two or more different regular polygons

10. Is this a semi-regular tesselation?

11. Why or why not?
