The ABC Toy Company is creating two similar pieces for a board game, as shown below. Find the value of x that makes the two pieces similar. (5 points) Triangle ABC is shown with sides AB marked as 6, BC marked as 7, and AC marked as y. Triangle DEF is shown with sides DE marked as 12, EF marked as x, and DF marked as z.

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.

example answer: "to determine if a sum is reasonable you can round each number to the nearest whole and compare the estimated sum to the actual sum."

hope this you and anyone else who needs the answer : ^)
