well the green and yellow triangles are placed in different places making it wider

they are the same shapes, the only difference is that in the second image the pink shape is measured on the bottom side while on the first image it was measured on the top. The bottom line is longer that the top.

it doesnt wrk because there’s a gap left over when u move the shapes around, equal to 1 square in that shape. It’s like a fake illusion… i also showed the class the impossible objects catagorie and the were FLABBAGASTED [if that's a wrd ;]]

Also, the thickness of the lines is important in that it HIDES the problem. By being extra thick, it covers up the whole that would be created if you actually cut the pieces from the first and tried to make the second

i think you just cut your figures wrong :D

Sure, the slopes are not the same by pitagoras, so sifferent figures will not align as on the picture.

Maybe all of you already know this,

the explanation is that the slope of the triangle objects in the two figures are not the same, so, that little difference results in an extra square measure unit in the second figure,

in other words, the objects forming the two figures are not same, they are bigger in the second figure.

the square are not squares !! if you have a form of square the result is lower than the other form…look to the squares of the whole table you will see it !

small typo: *The diagabal line on the RIGHT picture.
Sorry.

Guys, Adi is right.
The diaganal line on the left picture is not actually a straight line. You can calculate tangents of right angles of Blue and Yellow figures: 3/8(0.375) and 2/5(0.4) accordingly. So the angles are different and diaganal is not a straight line. It’s just an illusion ;)

Thanks! It was fun to solve it :)

The surface area of the second one is more that the first. by rearranging the blocks you can make change the surface area to be greater using the same blocks.
