step-by-step explanation:

mgxmgzmgzzzlgxhhhx. dlulhx

it is rigid.; it is isometric. ; the size is preserved.

step-by-step explanation:

a translation is called an isometry; these are transformations that preserve congruence between pre-images and images.

they are also called rigid transformations, as the only thing that can happen to a pre-image is that it is moved or turned, not stretched or shrunk.

since congruence is preserved, the size is preserved.

the answer is c.

perimeters = 3√10/5

areas = 90/25

i got it down chief.
