WebSo when you see a^2 that just means a square where the sides are length "a". The same would be true for b^2. The Pythagorean theorem states that the area of a square with "a" length sides plus the area of a square with "b" sides will be equal to the area of a square with "c" length sides or a^2+b^2=c^2. Bhaskara simply takes his square with ... WebDec 20, 2013 · These proofs, however, were in a very rigid format, with statements on the left side of the page and a reason for every statement on the right side.
