The Pythagorean Theorem
The following demonstration shows how the Pythagorean Theorem works. First, we must recall that the Pythagorean Theorem states that when the area of a square that is built upon the hypotenuse of a right triangle, will then equal the sums of the areas of the remaining built squares from the same right triangle. In this case, we have area of squares "RED" = c^2, area of square "GREEN" = a^2, and area of square"BLUE" = b^2. "Once the student drags on the "DRAG" point; the student shall see that the Pythagorean Theorem will always hold true.
