Made a new page: Pythagoras Theorem in 3D

Any suggestions or comments?

It's good, but I have a suggestion that in the animation when the purple and green squares cover the red one you should show the half line separating the purple and green squares to be equal halves. As of now, at the first glance I think students will think that the area of the purple and green squares equal the red one as you making things up since they can't see clearly that those squares are divided half and half. Sorry if my comment offends you in any way.

Actually I never watch Star Wars and not interested in it anyway, but I choose a Yoda card as my avatar in honor of our great friend bobbym who has passed away.

May his adventurous soul rest in peace at heaven.

Thanks ganesh!

No offence Monox! I am not sure what you mean by equal halves though.

Ummm... A line dividing the green square to two halves. The purple one should have that, too.

One of the best visual demonstrations of Pythagoras’s theorem I’ve ever seen was on *QI* a couple of years ago.
