regular and semi regular Tesselations

Regular Tessellating Shapes

A tessellation is a shape that fits together with out overlapping or
any gaps. There are not many regular shapes that can make a
tessellating pattern in fact there are only about four, a way to find
out is to choose a regular shape for instance square: there are
180degrees in a square so that means each interior angle must
equal 90degrees, in a tessellating pattern the squares join
together and form some vertices if you add all the interior angles
it will equal 360degrees this ap...
