all the lines together make up or loose the extra square..

its just like 1=2 i know how to prove it

its a paradox, it can be solved with Fibonacci numbers.

it isn't so logical, you have to draw a square with 64 little areas and cut them in pieces and rearrange them. you just will see a little square so you'll count 65 but when you calculate its 64.

paradoxes are fun

It's not a mystery

It's fairly simple, the outside area isn't perfectly square. The extra area adds up to about 1 cube, which is visible when rearranged properly.

FAIL!!!

3+3=7
Nothing to be proven here, it's just common sense

The slopes don't match. 2/5 != 3/8
The shapes don't fit together properly.

wtf

old trick
