3. Tessellations & Transformations
Tessellations can be modified by using transformations. As you know, transformations are movements of geometric figures. One transformation, commonly used to create tessellations is a slide, or translation, of a figure.

4. Translation Tessellations
For simple translation tessellations, polygons should have opposite sides that are parallel and congruent – squares, hexagons, parallelograms.

5. Example: Translation Tessellation
You can create more complex designs starting with square tessellations and making changes on both pairs of sides.

6. Depending how you decide to color your tessellation, a very simple design can have a very creative result.

7. Glide Reflection Tessellation
For glide reflection tessellations, polygons should have opposite sides that are parallel and congruent – squares, hexagons, parallelograms.

8. Example
By reflecting and gliding over more than one side, you can create a more complex tessellation.

9. Adding coloring and features will enhance the artwork.

10. Tessellation created by Rotation
Adjacent sides must be congruent – squares, equilateral triangles, regular hexagons, rhombi

11. Midpoint Rotations Triangles, Squares, and Quadrilaterals
Note: More than one side may be altered for more challenging designs. Coloring one side of the pattern will help prevent accidental flipping during tracing.

12. Example: Rotational Tessellation
