Question

Max is told that two triangles ΔXYZ and ΔSTU share 2 sets of congruent angles and one set of congruent sides: ∠X≅∠S, ∠Z≅∠U, XZ≅SU. Max concludes the triangles are congruent. Is Max correct? 

Answer 1

Yes; since the internal angles of a triangle is 180 degrees, the third angle is 180 minus the-other-two-angles. That means all three angle are the same. That is the very definition of congruence.

Answer 2

If you draw and label a diagram you should see congruence by ASA.
