We can do this by counting triangles
We can do this by counting triangles. The C-square is again made up of 4 triangles, plus the big red area in the middle. I propose that we now create a construct that is twice as large in area as C-square, and proof to ourselves that we can place two A-squares, and two B-squares into it. If we can do this, we have delivered proof of the Pythagorean theorem for all cases.
The proof lies in that we can prove that C-square covers precisely half of the area that we can place two A-squares, and two B-squares into.
