Question

What is true about every rotation?

A) The corresponding lengths, from the point of rotation, between the pre-image and image are preserved.

B) The image is smaller than the pre-image.

C) The image is larger than the pre-image.

D) The image is reduced or enlarged by a scale factor.

Answer 1

I believe the answer is A.

Answer 2

Answer: A) The corresponding lengths, from the point of rotation, between the pre-image and image are preserved.

Explanation:

A rotation is a rigid transformation that maps a figure by rotating it about some degrees from a particular point of rotation.

Since all the rigid motions produces congruent images. Therefore rotation too creates congruent images ( shape and size remains same) .

And corresponding sides of congruent images are also congruent.

Therefore, The corresponding lengths, from the point of rotation, between the pre-image and image are preserved.

Hence, the correct answer is option (A).
