Question

A rotation maps point A to A’.
Which statement describes the rotation?

A. 270° counterclockwise rotation

B. 90° clockwise rotation

C. 180° rotation

D. 90° counterclockwise rotation

Answer 1

C. 180° rotation .................

Answer 2

Answer:  The answer is (C) 180° rotation.

Step-by-step explanation:  Given that the point A maps to the point A' by a rotation. We are to select the statement that describes the rotation.

In the given figure, the co-ordinates of point A are (-3, 5) and after rotation, the co-ordinates of point A' are (3, -5).

Therefore, the point (x, y) changes to (-x, -y) after rotation. This is the result of 180° rotation.

Therefore, the point A is rotated through an angle of 180° to reach at the point A'.

Thus, the correct option is (C) 180° rotation.
