1. Curry's Paradox - How is it possible?

According to [|Martin Gardner], a New York city amateur magician Paul Curry invented the following paradox in 1953. A right triangle with legs 13 and 5 can be cut into two triangles (legs 8, 3 and 5, 2, respectively). The small triangles could be fitted into the angles of the given triangle in two different ways. In one case a a 5×3 rectangle of area 15 is left over. In the other case, we get an 8×2 rectangle of area 16.
