Answer:
angle EDA congruent to angle FDC because vertical angles
Trangle ADE is congruent to CDF because ASA congruence
Explanation:
angle EDA will always be congruent to angle FDC cause they're made up of the same lines forming 2 angles (vertical angles)
and then you have 2 angles as one side which is enough to prove they're congruent and the proved angles/sides are in the order Angle Side Angle (ASA)
probably didn't make sense but hope it did
