Answer:
ASA
Explanation:
When you look at the picture, you can see that both the triangles have congruent angles (top and bottom). They also share the same side (middle line). So it would be angle, side, angle.
Angles B are congruent with each other and angles D are congruent with each other since they have the same markings. Since the triangles share the same middle line, then that makes the markings the same, or congruent.
