Triangle Congruence - SSS and SAS. We have learned that triangles are congruent if their corresponding sides and angles are congruent. However, there are excessive requirements that need to be met in order for this claim to hold. In this section, we will learn two postulates that prove triangles congruent with less information required.
Now we have two angles and a side! So we can say that triangle MNQ is congruent to triangle POQ because of the AAS theorem. And therefore, MN is congruent to OP because corresponding parts of congruent triangles are congruent, or CPCTC.
