Line segment ST is dilated to create line segment S'T' using the dilation rule DQ,2.25. Point Q is the center of dilation. Line segment S T is dilated to create line segment S prime T prime. The length of Q T is 1.2 and the length of Q S is 2. The length of S S prime is x and the length of T T prime is 1.5. What is x, the distance between points S' and S?

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.
