15. Which

transformation does not preserve distance?

b. Rotation of 90° CW
c. Translation down 3 units
d. Dilation by a scale factor of 3

Answer 1

D Dilation by a scale factor of 3

Explanation:

Reflections, Rotations and Translations are rigid transformations. They do not change the size of the figure. I dilation with shrink or expand a figure by the scale factor so the distances will not remain the same.
