Fibonacci...64=65 - May 29th 2009, 11:03 PM

I'm doing a poject on Fibonacci, and I was wondering if anyone knows the 64=65 square-rectangle thing?
Heres a link.

The explanation is a bit over my head because I don't really understand much about Fibonacci, but this site: http://www.cut-the-knot.org/Generali...Plus.shtml#bam might have what you're looking for (it looks like it's just all a trick, though the site explains why it works...). Hope this helps. ^_^

Wow I've never seen this problem before. It's just a trick on your eyes, it took me a little while of staring at it to figure out what's going on, but the slope between the triangles and the other polygons cause a square to be lost. It just takes a bit of staring at it.
