All squares are the same but....You have not put the orange on top of the green....like in the first example.

:)

 
I dont care I am sick of looking at it and I hate puzzles anyway :)

 
The hypotenuse on the top figure is slightly concave, on the bottom figure, it's slightly convex.  Different areas.  :huh:

 
Guys all the bits are identical. It is an optical illusion to make you think it is one square gap missing....it is not ....you put the orange on top of the green not just slid up to it.... L. O. L. Then you swap the two triangles.

Simples..click...!

 
The top line isn't straight, the angle of the triangles is different so on the top one the top line "bows" in and on the bottom one it "bows" out allowing the extra volume equal to one square of that makes sense

 
Hahahahahahahahaha ha

I cannot believe that you are not getting this.... L. O. L.

 
The key to the puzzle is the fact that neither of the 13×5 "triangles" is truly a triangle, because what would be the hypotenuse is bent. In other words, the hypotenuse does not maintain a consistent slope, even though it may appear that way to the human eye. A true 13×5 triangle cannot be created from the given component parts.

The four figures (the yellow, red, blue and green shapes) total 32 units of area. The apparent triangles formed from the figures are 13 units wide and 5 units tall, so it appears that the area should be units. However the blue triangle has a ratio of 5:2 (=2.5:1), while the red triangle has the ratio 8:3 (≈2.667:1), so the apparent combined hypotenuse in each figure is actually bent.

The amount of bending is around 1/28th of a unit (1.245364267°), which is difficult to see on the diagram of this puzzle. Note the grid point where the red and blue hypotenuses meet, and compare it to the same point on the other figure; the edge is slightly over or under the mark. Overlaying the hypotenuses from both figures results in a very thin parallelogram with the area of exactly one grid square, the same area "missing" from the second figure.

According to Martin Gardner, this particular puzzle was invented by a New York City amateur magician, Paul Curry, in 1953. The principle of a dissection paradox has however been known since the start of the 16th century.

The integer dimensions of the parts of the puzzle (2, 3, 5, 8, 13) are successive Fibonacci numbers. Many other geometric dissection puzzles are based on a few simple properties of the famous Fibonacci sequence.

Brilliant answer....you got the turkey....can I come for lunch ?

Is that another way of saying the hypoteneses aren't straight? :p
