PLEASE HELP!
Vlad [161]

Answer:

Option A. ∠C and ∠C'' are congruent after both the translation and the dilation

Step-by-step explanation:

we know that

The translation is a rigid transformation. After the translation the image and the pre-image are congruent

The dilation is a non rigid transformation. After the dilation the image and the pre-image are similar

Remember that

If two figures are similar, then its corresponding angles are congruent and the ratio of its corresponding sides is proportional

If two figures are congruent, then its corresponding angles and corresponding sides are congruent

therefore

∠C and ∠C'' are congruent after both the translation and the dilation
