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
