Find the value of the variable for each angle in an equilateral triangle.
7x+9
6y - 14
3z +5

no, x cannot be the same number. in all of them, x is 1. for one input there is another output. g is not a function

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.
