Congruent angles
1. We can see in the figure that:
the red angle is the same for both triangles.
2. We observe that:
they share the same side.
3. Finally, we see that:
the blue angle is the same for both triangles.
Then, they have they both have two equal angles and one equal side:
This is Angle - Side- Angle: ASA
Answer- A: ASA
