That is also a visual proof of the Pythagorean theorem for the 45-45-90 special case.

Here is a visual proof of the Pythagorean theorem for arbitrary lengths of two sides. The two black squares have the same total area as the green square which is also on the hypotenuse of the right triangle formed by the two shorter lengths:



The pattern also works as a way to tile a room with two batches of square tiles of different sizes.

i'VE FOUND OLDER THREADS TO SOMETIMES BE INTERESTING.

seems fine to me if i dont want to read it i can close it or pass it. plus it can bring in new comers to the site that otherwise may not join and contribute.
there is no downside to it except for those that dont see its old and get upset for some reason.

some of the old threads are amazing and forgotten about and deserved to be resurrected.

I know the for sale section gets messy with several year old items which haven't sold and keep getting bumped.
