The rule (x,y)→(2x,2y) maps △DEF to △D′E′F′.Which statement correctly describes the relationship between △DEF and △D′E′F′ ? The triangles are not congruent because △D′E′F′ is a translation of △DEF , and a translation is not a rigid motion. The triangles are congruent because △D′E′F′ is a rotation of △DEF , and a rotation is a rigid motion. The triangles are not congruent because △D′E′F′ is a dilation of △DEF , and a dilation is not a rigid motion. The triangles are congruent because △D′E′F′ is a reflection of △DEF , and a reflection is a rigid motion.
