Question

 A dilation with a scale factor of 2 maps ABC to DEF. Which best compares m <B to m<E?

A. m<B = 2(m < E)

B. m<E = 2(m <B)

C. m<E = 180 - m<B

D. m<B = m<E

Answer 1

Since a dilation changes all sides equally, the image is similar to the object. Hence corresponding angles remain congruent and their measures are equal.
