To prove that triangles \( \triangle ABC \) and \( \triangle QRS \) are congruent by the Angle-Side-Angle (ASA) Congruence Theorem, you need the following information:

  • You must have one pair of corresponding angles that are congruent.
  • The length of the side that is included between those angles must be congruent.
  • You need one more pair of corresponding angles to be congruent.

From your options, you have:

  1. If \( \angle C \cong \angle S \) (one pair of congruent angles).
  2. A side included between those angles: either \( AC \cong QS \) or \( AB \cong QR \).
  3. A second pair of angles: \( \angle A \cong \angle Q \) or \( \angle B \cong \angle R \) (this would provide the second congruent angle required for the ASA).

To succinctly state which specific additional information would complete the requirement:

  • If you confirm \( \angle A \cong \angle Q \) (or another corresponding angle) along with one of the congruent sides (like \( AC \cong QS \)), then you would have everything needed for ASA.

Thus, any response indicating a congruent angle or a congruent side paired with the congruent angle should be chosen.
