Question

choose 1 answer:
a translation
b rotation
c reflection
d dilation

Explanation:

Translation, rotation, and reflection are rigid transformations that preserve the size and shape of a figure. Here, triangle B is smaller than triangle A, so these do not apply. Dilation is a transformation that changes the size of a figure while keeping its shape, which matches the relationship between the two triangles.

Answer:

D. Dilation
