To prove that triangle \( \triangle ABC \) is congruent to triangle \( \triangle QRS \) using the Angle-Side-Angle (ASA) Congruence Theorem, you need two angles and the side between them to be congruent for the triangles.

Based on the information provided, you have:

1. \( AC \cong QS \) (Side)
2. \( \angle C \cong \angle S \) (Angle)
3. \( BC \cong RS \) (Side)
4. \( AB \cong QR \) (Side)

To apply the ASA Congruence Criterion, you would need specifically that:

- One angle (e.g., \( \angle C \)) is congruent to another angle (e.g., \( \angle S \)).
- The sides forming these angles (in this case, \( AC \) and \( BC \) corresponding to \( QS \) and \( RS \)) must be involved.

In this scenario, you already have:

- One angle \( \angle C \cong \angle S \).
- The two sides \( AC \cong QS \) and \( BC \cong RS \) can serve as the sides adjacent to these angles.

The additional information that you might need (not provided in this case) could include the lengths or relationships between the sides and angles to confirm that the arrangement indeed creates a condition where they are congruent triangles through ASA. However, your existing information points to likely congruence as it stands.

So to directly answer your question, you might affirmatively state that:

You already have enough information to prove that \( \triangle ABC \cong \triangle QRS \) by ASA. You have the angle \( \angle C \) and side \( AC \) congruent to angle \( \angle S \) and side \( QS \) respectively, with side \( BC \) also congruent to \( RS \), confirming the ASA structure.
