Triangle XYZ is translated by the rule (x + 1, y − 1) and then dilated by a scale factor of 4 centered at the origin. Which statement describes the properties of triangles XYZ and X''Y''Z'' after the transformations? A) Y and ∠Y'' are congruent after the translation, but not after the dilation. B) ∠Y and ∠Y'' are congruent after the dilation, but not after the translation. C) segment YZ and segment Y double prime Z double prime are proportional after the translation, but not after the dilation. D) segment YZ and segment Y double prime Z double prime are proportional after the dilation and congruent after the translation.
