Question

point q was rotated by $-150^circ$ (the center of rotation is indicated).
which point is the image of q?
choose 1 answer:
a $a$
b $b$
c $c$
d $d$

Explanation:

Step1: Understand rotation direction

A negative angle ($-150^\circ$) means clockwise rotation around the center.

Step2: Estimate rotation magnitude

Measure/estimate the $150^\circ$ clockwise turn from point Q around the center. A $180^\circ$ clockwise turn would point opposite Q, so $150^\circ$ is a short counter-clockwise adjustment from that opposite direction, landing on point B.

Answer:

B. B
