The point (3, 2) is turned 90 degrees clockwise about the origin. What are its new coordinates?
Answer and explanation
Correct answer: C. (2, -3)
- Step 1: A 90 degree clockwise turn about the origin maps (x, y) to (y, -x).
- Step 2: So (3, 2) becomes (2, -3).
Answer
(2, -3).
Why not the others: (-2, 3) is a 90 degree anticlockwise turn, (-3, -2) is a half turn and (3, -2) is a reflection in the x-axis.
