tessellate. For a shape to be tessellated, the angles around every point must add up to 360◦. A regular pentagon does
not tessellate by itself. But, if we add in another shape, a rhombus, for example, then the two shapes together will
tessellate.
Tessellations can also be much more complicated. Here are a couple of examples.
Example A
Tessellate the quadrilateral below.
To tessellate any image you will need to reflect and rotate the image so that the sides all fit together. First, start by
matching up each side with itself around the quadrilateral.
This is the final tessellation. You can continue to tessellate this shape forever.
Now, continue to fill in around the figures with either the original or the rotation.
