rolf Posted September 7, 2011 Posted September 7, 2011 @Joker: spoilerfail Reveal hidden contents The sharp angle of the green is acos(2/5) = 66 degree. The sharp angle of the yellow triangle is acos(3/8) = 68 degree. That actually means that the line from leftmost to rightmost is not straight. However, in the first triangle that means that there is a slight 'dip' (or whatever you would call it) on the intersection of yellow and green, which means it's smaller than the second, which has a small bump on the intersection on yellow and green. Although I wouldn't imagine the difference is that big, apparently it is Quote

The task is that answer how can be there an empty box if every piece is same size only on different spot? @rolf fail? I would totally understand the solution from my answer. Maybe it could be composed better but sometimes words Im looking for doesnt cross my mind Quote

Well duh because the 2 triangles switches the other two had to be on diff places too and they have weird shapes so then it has an empty one..idk how to explain, but this is not a mindblow thing if u have a lil bit of sense lol Quote
