Which characteristic does a translation not preserve? . a) distance from the origin. b) size of the figure. c) rotational symmetry. d) shape.

A translation does not preserve distance from the origin because translation is the term that is used to move the  graph and every point of object have to move so it does not preserve the distance from the origin
so i conclude option A is correct from above
hope it helps!
