Answer:
1. You would be able to conclude that the triangles are congruent by HL congruence theorem if you also knew that side RT was congruent to VT
Explanation:
You can use the hypotenuse-leg theorem if you have side RT=VT because that side is the hypotenuse and you already have one leg.
Answer:
2. AAS congruence postulate
Explanation:
The diagram shows that a side and angle are congruent and we know that vertical angles are congruent so ∠RTS=∠UTV.
