what is true about every rotation? the image and pre-image are congruent. the image is larger than the pre-image. the image overlaps the pre-image. the image is smaller than the pre-image.
I think the correct answer from the choices listed above is the first option. The statement that is true for every rotation would be that the image and pre-image are congruent. All the rest deals with changing the rotated shape not a constant. Hope this helps.
