1
2

Answer:

Option D) The angle measurements are unchanged.

Step-by-step explanation:

we know that

A dilation is a non-rigid transformation that produces an image that is the same shape as the original, but is a different size, so produces similar figures.

Remember that, if two figures are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent.

therefore

The angle measurements are unchanged

Answer:D

The ANGLE measurement of the dilation does not change, the length changes.
