You probably don't notice it but the pieces actually don't fit together when you rearrange them (because the diagonal in the rectangle (the new figure) is not really a line). It is very subtle but if you do the math, you'll see what I mean. Don't just trust in what you see.

Yes, had a good laugh when I 1st saw this.

While I've seen this idea before, that was a cute little animation. Thanks.

Ah, the difference between 0.4 and 0.375... so close, yet so far.

there is also a nice proof that all angles are right angles that I have always been puzzled by, that depends on a picture. I never can recall how it goes.

I was fooled by a similar problem awhile back, so it was easy to spot the flaw in this one. That and the gap between purported straight lines was larger.
