Question

Quadrilateral A B C D is the image of a quadrilateral ABCD under a rotation about point P

Determine the angle of the rotation
-105
-75
75
105

Answer 1

• D. 105°

Explanation:

If we connect points C and C' with the center of rotation P, the angle CPC' appears greater than 90°, so the angle could be 105° or - 105°

Since the rotation is counterclockwise the angle of rotation is deemed as positive.

Correct choice is D.
