Answer:
SAS
Explanation:
We know that segment PR is congruent to segment SQ, because of the a line bisects the segment the segments are on. We also know that angle PRQ is congruent to angle SRQ, because of the reflexive property. Using the same property, QR is congruent too QR.
By knowing that, we can conclude that the two triangles are congruent because of SAS.
