Answer: B. same distance

There is the same distance between the point on the preimage to the center of rotation and that of the distance from the corresponding point on the image to the center of rotation. There is change in the distance of the two.

Answer: B. same distance

Explanation:

The rotation consists on the angular motion of the points of the preimage.

Therefore, the center of rotation is fixed and each point is transported a number of degrees (counter-clockwise or clockwise), keeping fixed the distance from the center of rotation.

It is exactly like making a circle but you stop before completing the circle, when you have rotated the amount of degress (angle) desired.
