Exercise 18 Page 649

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.
