2. What is a Tessellation? A tessellation is a pattern of repeating shapes that leave no spaces or overlaps in it pieces. Tessellations are made by reflecting (flipping), translating (sliding) and rotating (turning) the shapes chosen.

3. Perfect Tessellations Perfect tessellations are formed from only one type of shape.

4. Semi-Regular Tessellations Semi-regular tessellations are formed when two or more shapes are used to tessellate. The tessellation is like a cycle where the same shape is surrounded by several of another shape.

5. Non regular Tessellations Non regular tessellations occur with no restrictions. Any shape can be used in any way.
