A place for students to explore mathematics.
Very nice idea sir
Sanjay,I think the usual way to show this geometrically is to draw it with the b x b square in the upper right hand corner. (In other words, remove points E and D and extend CB to meet QR at D). To me this is clearer. Is there some special reason you put the square in the lower right hand corner?
There is no specific reason for putting b x b there. Point A is a variable point you can drag it with your mouse.
....but ther is a very good reason to put it where Petersuggests - it makes it clear, obvious and easy, as opposed to arbitary and complicated.I like Sanjay's square of difference though.
