Question

How do I solve this?

Answer 1

you have to prove they are similar

Answer 2

How do I do that?

Answer 3

well you have congruent triangles over a straight line
you can prove the opposite angle being equal and lines in ratio

Answer 4

@CaseyCarns angle ACB = angle GCE...and angle BAC = angle CGE..so by AA similarity

Answer 5

@rishavraj is that my entire answer?

Answer 6

makes sense
they are congruent
so AB is parallel to DG
alternate angles are equal
good one @rishavraj

Answer 7

yes

Answer 8

two angles are equal
ultlimately 3rd angle will be equal
so they are similar
