∆ABC is translated 2 units down and 1 unit to the left. Then it is rotated 90° clockwise about the origin to form ∆A′B′C′.

The coordinates of vertex A′ of ∆A′B′C′ are (-2, 0)(2, 1)(-1, -2)(-2, 1).The coordinates of vertex B′ of ∆A′B′C′ are (1, -1)(1, 0)(5, 0)(2, -3).The coordinates of vertex C′ of ∆A′B′C′ are (-1, -1)(3, 0)(-1, 0)(0, -3).
