To determine which pairs of triangles can be proven congruent using the ASA (Angle-Side-Angle) congruence theorem, we must look for pairs where two angles and the included side (the side between the two angles) of one triangle correspond to two angles and the included side of another triangle.
From the description you provided:
- Triangles XYZ and ABC - Two congruent triangles (no specific markings indicated).
- Triangles ABC and QRS - Side AC and QS are marked congruent.
- Another pair of triangles (same as the first).
- Another pair of triangles (same as the second).
For triangles to be proven congruent by ASA, we need:
- Two angles: You must have information about two angles for each triangle.
- The included side: The side between the two angles must also be marked as congruent.
So, for option 2, where the side AC is congruent to side QS, we would need to know if there are angles at vertices A and B, and another angle at vertex C, corresponding to angles at vertices Q and R, and another angle at vertex S that are also congruent.
If this is the case, triangles ABC and QRS can be proven congruent by the ASA theorem.
Without the images or specific markings for angles, I cannot definitively state which pair(s) are congruent, but look for two angles around the marked sides in any diagrams you have. If the required conditions for ASA are met in either of the provided pairs, then that pair could be proven congruent.
