Pythagorean Theorem

1. Construct a small square CEFD (side length of 1.52) and a big square GIJH (side length of 3.86). 2. Translate the small square in such a way that point E is at point H of the big square and their diagonals are collinear. (line segments DE and HI). 3. Join LJ and construct a square with line segment LJ as a side. 4. Then, get the area of each square. 5. Therefore, the whole square LJPO equals the sum of the two squares.
