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.
