Respuesta :

Answer:

D Dilation by a scale factor of 3

Step-by-step 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.
