The diagonals of the blue shape and the green shape (and likewise of the red and the orange) in the 5 x 13 figure look like they match up, but they actually don't. There's a narrow gap between them, too narrow to see easily, but when it's added up over

No, Manhung is right. Here's how it happens. When the pieces break off, the edge where it was broken gets thicker. But when the pieces are put back together they're put back with these larger pieces. This extra space, added up among all the lines, accou

There is an area equal to one whole block missing smack dab in the middle of the diagonal "line." It is especially clear when they show the two blocks next to eachother.

The slope of the lines are 3/8 and 2/5 so they don't line up perfectly, leaving a thin gap which is hidden by the outlines.

Yeah. If you look at the long diagonal on the rectangle, notice how the line is thicker in the middle and thin on the ends. It took me three minutes of staring to figure it out.

its an optical illusion. Check your rises over runs and you'll find that one of the lines is not a line at all and is not straight. Though it was very clever :)

The slope of the diagonal between the red and green triangles comes out to two point six repeating (2.67~). The slope of the diagonals between the blue and orange is exactly two point five (2.5). When the shape is repositioned, the gap between the shapes

Bah, not this optical illusion again. The two 5x8 "triangles" which make up the 5x8 rectangle are not in fact triangles. If you were to view a high resolution image of the two triangles you would see that they are actually quadrilaterals and not trian

Notice: The slope of blue/orange is 2/5, while red/green is 3/8. While they are very close, they could vener fit, due to the fact that they are different slopes

Those are triangles. They're quadrilaterals. If you look REALLY closely, you can see that the triangles are either convex or concave slightly. It's an illusion. 1 for wasted effort.

I liked it, showed my math professor, he says it's called a "Fudge" factor. Someone mentioned how the edges are stretched already. Lousy optical illusions.

Different dimentions. 8x8 as a whole square grid would produce 64. It's different when you separate them into pieces, since you get different results, depending on the way you cut the grid into pieces. More like logic, if you think about it. ;)

It's pretty easy to spot the error, even by visual inspection. 3/8 != 2/5, so the slopes don't match up exactly.

Awesome find, I give it five stars, but unfortuantely, there is an explanation. *sigh* Anyway, the slope of the diagonal line of the triangle and the diagonal line of the trapezoid aren't the same, they are slightly off. When you put the two triangles and trapezoids back together for the rectangle, the diagonal line is in fact not a line at all, but a paralellogram with an area of 1. I'm surprised no one explained this yet.

The fractional difference in slopes along the diagonal in the new rectangle add up to exactly 1.
