Final answer:
To properly prove that triangle QPR is congruent to triangle PSR, more information is required regarding the congruent sides and angles in order to apply the correct congruence postulate: ASA, SAS, AAS, or SSS.
Step-by-step explanation:
To determine which postulate would prove that triangle QPR ≡ triangle PSR, we need to know what aspects of the triangles are given to be congruent. The abbreviations stand for:
- ASA (Angle-Side-Angle)
- SAS (Side-Angle-Side)
- AAS (Angle-Angle-Side)
- SSS (Side-Side-Side)
Without specific information about the congruencies of sides and angles in triangles QPR and PSR, we cannot definitively choose the right postulate. Each option refers to a different set of criteria:
- ASA: Two angles and the included side are the same.
- SAS: Two sides and the included angle are the same.
- AAS: Two angles and a non-included side are the same.
- SSS: All three sides are the same length.
For a precise answer, more details are needed about the congruent parts of the given triangles.
