a < b < c so the Pythagorean theorem holds true.
The four yellow triangles are congruent in both large squares and the large squares are congruent, so c ^ 2 = a ^ 2 + b ^ 2
a = b = c so the Pythagorean theorem holds true.
The yellow triangles fill'up the large squares just enough to have a small square in each figure.
