In the diagram, AABC and ADBE are similar. What is the scale factor of the dilation that will map the prelmage AABC onto the image ADBE?

i think it’s a i believe

this is a good question! i’ll do some research and what i find, i’ll contact you asap when i have something! ✊

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.
