How many congruent angles do you see in the diagram?
Not enough information. Explanation: See solution.
Practice makes perfect
Examining the diagram in the exercise, we see that the two triangles have one pair of congruent angles and one pair of congruent sides:
∠T ≅ ∠Q and TU≅QR
This is not enough information to claim congruence by the AAS Congruence Theorem.
