A fur dresser had to put a patch shaped like a scalene triangle on a piece of fur. Suddenly he realized he had made a terrible mistake. The patch fitted the hole but the fur side faced the wrong way.
The fur dresser, after some thought, cut the triangular patch into 3 parts, each of which would be unchanged when turned over. How?
on the hide side, he draws a line from each vertex, bisecting the angle of each. these lines meet at a ‘center’ point, from which he draws three lines, one to each of the sides, perpendicular so as to meet the sides at right angles. cutting along these lines he is left with three symmetrical quadrangles, which are the same shape when flipped on the axes created by the first set of lines.
