ASA Postulate (Angle-Side-Angle)
If two angles and the included side of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.
You have that ∠C and ∠Q are congruent. In order to use ASA Postulate, you should have:
1. ∠B and ∠P are congruent and BC=PQ (choice 1)
2. ∠A and ∠T are congruent and AC=TQ (choice 2)
AAS Postulate (Angle-Angle-Side)
If two angles and a non-included side of one triangle are congruent to the corresponding parts of another triangle, then the triangles are congruent.
In order to use AAS Postulate, you should have:
1. ∠A and ∠T are congruent and BC=PQ (choice 4);
2. ∠B and ∠P are congruent and AC=TQ;
Answer: correct options are 1, 2, 4.
