Which statement is used to prove that angle ABD is congruent to angle ACD? (4 points)

Triangle ACD is similar to triangle ABD.

Segment AD is congruent to segment AC.

Angle DAC is congruent to angle DAB.

Angle CAB is congruent to angle CBA.

I think it could be the 1st option because that's how you would end the proof or third option since D is the mid point. Please help
