Question

ΔABC is translated 2 units down and 1 unit left. Then it is rotated 90° clockwise about the origin to create ΔA′B′C′. What are the coordinates of the vertices of ΔA′B′C′ ?

A'(-2, 0), B'(1, -1), C'(-1, -1)

A'(2, 1), B'(5, 0), C'(3, 0)

A'(-1, -2), B'(2, -3), C'(0, -3)

A'(-2, 1), B'(1, 0), C'(-1, 0)
