does anyone know if you can use the method with the square at an angle insie another square and the four triangles (im not sure what the metho is called )

Adamstown we learned the theorem in the format you have descrined above but after our mocks our teacher told us there is only 1 acceptable proof for project maths and in that proof you use similar triangles and ratios

This website is good for other maths proofs
