Triangle 1 has vertices at (A, B), (C, D), and (E, F).
Triangle 2 has vertices at (-A, B), (-C, D), and (-E, F).
What can you conclude about triangle 2?

A) Triangle 2 is congruent to
triangle 1 because a translation
is a rigid motion.

B) You cannot tell because you do
not know where the points are in
the plane.

C)Triangle 2 is not congruent to
triangle 1 because a dilation is
not a rigid motion.

D)Triangle 2 is congruent to
triangle 1 because a reflection is
a rigid motion.
