Question

HELP!!!

Answer 1

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