Triangles RQS and NTV have the following characteristics:

• Right angles at ∠Q and ∠T
• RQ ≅ NT

Can it be concluded that ΔRQS ≅ ΔNTV by SAS? Why or why not?

No. SAS requires two pairs of corresponding sides and the included angle between them. Here you are only given one pair of congruent sides (RQ ≅ NT) and that the corresponding angles are right angles. That is only one side and one angle, not two sides with the angle between them, so SAS does not apply.

Counterexample: Let RQ = NT = 3, QS = 4, and TV = 5. Both ∠Q and ∠T are right angles, but ΔRQS (legs 3 and 4, hypotenuse 5) is not congruent to ΔNTV (legs 3 and 5, hypotenuse √34). Thus the given information is insufficient for congruence by SAS.
