Answer:
1: Side-Side-Side theorem
2: Side-Angle-Side theorem
3: Angle-Side-Angle theorum
4: Side-Angle-Angle theorum
Step-by-step explanation:
Look at the order of the sides and/or angles of the triangles. Because both of the triangles have the same sides/angles based off either the side-side-side, side-angle-side, angle-side-angle, or side-angle-angle theorem, they are congruent.
Hope this helps! :)
