Take a square and cut it as you wish into a finite number of pieces. Rearrange the pieces without rotating or flipping any of them to form an new square that is rotated 45-degrees compared to the original.

Say you cut the square into four equal squares.  Then put the move the square going clockwise.  For instance, putting the square thats in quadrant III in Quadrant IV, the one that was in IV would go to I, the one in I would go to II, and the one in II would go to III.  Is that right?
