Respuesta :

Answer:

Option (D)

Step-by-step explanation:

Vertices of triangle D'E'F" are formed by shifting ΔDEF 6 units up vertically, transformation will be defined as translation.

Translation, rotation and reflection are the rigid transformations.

And in rigid transformations image and preimage are congruent to each other.

Therefore, ΔD'E'F' is congruent to ΔDEF.

Option (D) will be the answer.
