Triangle pqr is translated by the rule (x − 1, y − 1) and then dilated by a scale factor of 3 centered at the origin. which statement describes the properties of triangles pqr and p''q''r'' after the transformations? ∠p and ∠p'' are congruent after the translation, but not after the dilation. ∠p and ∠p'' are congruent after the dilation, but not after the translation. segment pq and segment p double prime q double prime are congruent after the translation, but not after the dilation. segment pq and segment p double prime q double prime are congruent after the dilation, but not after the translation.
