Question

Triangle ABC is dilated so that the side lengths of the image are three times the lengths of their corresponding sides. Which of the following statements are true? Select all that apply.

AB ≅ A'B'
CB ~ C'B'
∠A ≅ ∠A'
CA ≅ C'A'
∠B ~ ∠B'

Answer 1

∠A ≅ ∠A' and CB ~ C'B'

Explanation:

Answer 2

∠A ≅ ∠A' and CB ~ C'B'

Explanation:

In a dilation, you get a SIMILAR figure. It will have the same shape, but a different size.

Similar figures have the same angle measures but the side lengths will change.

Any of the answers with congruent (≅) angles are correct:

∠A ≅ ∠A'

Any of the answers with SIMILAR (~) side lengths are correct:

CB ~ C'B'
