Answer:
Segment AC is congruent to segment AC
Step-by-step explanation:
The ASA postulate is Angle-Side-Angle, which means that if there are two angles on one triangle as well as a side in between those that are ALL congruent to two angles and a side on the other triangle, then the two triangles are congruent, or equal.
You already know that and angle in both triangles is 30 degrees and another pair is 40 degrees, so you have to know the side in between those angles.
The reflexive property states that since the two triangles share the side, it is congruent between both triangles. That side is segment AC.
So AC is congruent to AC
So your answer would be the third choice
