Pythagorean Theorem Graphical Proof[br][br]1. Try adjusting the angle by manipulating the slider. Make the angle less than 90 or more than 90.[br]2. Try changing the size of the right triangle by dragging the points on the triangle. [br]3. Watch the graphical proof by clicking on "Step" one at a time.
Does Pythagoras relationship work if you change the size of the right triangle? (Check if a^2+b^2 = c^2 hold as you change the size of the right triangle.)
At the end of step 6, two large squares are formed. How does it prove the Pythagorean Theorem? Explain.
