Question

The rule (x,y)→(2x,2y)(x,y)→(2x,2y) maps △DEF△DEF to △D′E′F′△D′E′F′.

Which statement correctly describes the relationship between △DEF and △D′E′F′ ?

A. The triangles are congruent because △D′E′F′ is a reflection of △DEF , and a reflection is a rigid motion.

B. The triangles are not congruent because △D′E′F′ is a translation of △DEF , and a translation is not a rigid motion.

C. The triangles are not congruent because △D′E′F′ is a dilation of △DEF , and a dilation is not a rigid motion.

D. The triangles are congruent because △D′E′F′ is a ridgid motion.
