Question

Demonstrating the properties of rotations, if a line segment with endpoints (0, −3) and (0, −7) is 90° clockwise, what is an endpoint of this rotated segment?
A. (3, 0)
B. (0, 7)
C. (-3, 0)
D. (0, 3)

Answer 1

Rotate each point 90° clockwise: (x,y) → (y, −x).
(0, −3) → (−3, 0).
So an endpoint is (−3, 0), choice C.
