I am very, very confused about proofs, and do not have much time to finish them! I would appreciate any help and explaination. Please see the attachment for the problem as it has a picture. Thank you so much for anyone's help!!
Here is a summary that should help you out. I didn't use all the information because I didn't see the need to.
-Prove that triangle AGF is congruent to triangle CGF (via ASA or AAS)
-Line GA = Line GC (corresponding side of congruent triangles AGF and CGF)
-Therefore triangle AGC is isoceles (1 pair of equal sides)
