What is the math behind the concept of tesselations?
When polygons are set out on a plane they must not overlap and have no gaps
What is the number of polygon sides can be used for tesselations?
For regular polygons: 3, 4, or 6. For irregular polygons, figures with any number of sides can be found.
Will a pattern of right triangles and squares tessellate?
Yes. Consider the situation when: the right-angled triangles are also isosceles and the hypotenuse (longest side) of the triangles is equal to the side of the square. If you surround a square with four of right-angled triangles (the sides of the square being in contact with the hypotenuses of the triangles), you get a larger shape which is also a square. Taking this as a basic unit, you can make a tesselations. You can also make tessalations if you have two sets of squares, one with sides the same length of the hypotenuse of the triangles and one with sides the same length as the smaller sides of the triangles.
