∠C and ∠C'' are congruent after both the translation and the dilation.
 ∠C and ∠C'' are congruent after the dilation, but not after the translation.
 segment AC and segment A double prime C double prime are congruent after both the translation and the dilation.
 segment AC and segment A double prime C double prime are congruent after the dilation, but not after the translation.
