Tammy was curious if quadrilaterals ABCDABCDA, B, C, D and FGHEFGHEF, G, H, E were congruent. She was able to map one figure onto the other using a reflection and a translation.

Tammy concluded:
"I was able to map quadrilateral ABCDABCDA, B, C, D onto FGHEFGHEF, G, H, E using a sequence of rigid transformations, so the figures are congruent."
What error did Tammy make in her conclusion?
Choose 1
Choose 1

(Choice A)
A
Tammy didn't use only rigid transformations, so the figures are not congruent.

(Choice B)
B
It's possible to map to map quadrilateral ABCDABCDA, B, C, D onto FGHEFGHEF, G, H, E using a sequence of rigid transformations, but the figures are not congruent.

(Choice C)
C
There is no error. This is a correct conclusion.
