Question

ΔABC rotates 90° clockwise about point P to produce ΔA'B'C'. What is m∠CPC'? A. 50° B. 60° C. 70° D. 90°

Answer 1

I think the best answer to it is letter D. 90degrees because the P is the point of rotation by 90 degree so it means when C' is form the vertex is P and the angle that is formed by the 2 sides is 90. I hope you are satisfied with my answer and feel free to ask for more.

Answer 2

The correct answer is:

D. 90°

Step-by-step explanation:

The measure of the angle from the pre-image point C to the image point C' through the center of rotation, P, will be the same as the angle of rotation. Since the measure of the angle of rotation is 90°, then the measure of angle CPC' will also be 90°.
