A transformation of KLM results in K'L'M'. Which transformation maps the pre-image to the image? a. dilation
b. translation
c. reflection
d. rotation

a. dilation.

Step-by-step explanation:

In this problem, the triangle has been neither reflected nor rotated. Although you could say the triangle has been translated, translation will preserve the lengths of the legs of the triangle.

Since all the angles are still congruent, we can say that the triangle has been dilated. It has been enlarged.

Hope this helps!
