Answer:
By AAS or AAA congruence, you can prove it.
I hope it will be useful .
Explanation:
angleG=angleE (given)
Corresponding opposite angles formed by the transversal are equal! i.e., angleFDG=angleDFE or vice-versa..
And the side is common! or you can prove it by AAA criteria (two pairs of equal angles made by the transversal)
