12.1 MATH

A tessellation is a pattern made of identical shapes. You can make your own tessellation by fitting copies of a shape together, without gaps or overlaps. You say the shape tessellates, or is a tessellating shape.

Here are some examples of shapes that tessellate with themselves and not with them self=


When you make a tessellation are made by repeating a shape and using half-turn rotations of the same shape. For examples, this triangleand a half-turn rotation of the same trianglefit together exactly to make a tessellation like this. 
In any tessellation, the sum of the angles at the point where the vertices of the shape is 360°
