hi dear,
If you translate the trapezoid 3 units to the left the new vertices would be (-2,-2), (-2,-4), (0,-1) and (0,-5). Now draw it on a piece of paper and rotate.
If you rotate 90 degree the new vertices would be (1,0), (2,-2), (4,-2) and (5,0).
If the trapzoid is rotated to 180 degree the new vertices would be (0,1), (2,2),(2,4) and (0,5).
