The two triangles are congruent through SSA
Here, we want to prove the equality of two triangles
From the diagram, we can see thaT QP is common to both triangles
What this mean is that we have two equal sides already
Lastly, we can see that since RQS is bisected, then equal measure of the parent angle RQS lies in both triangles
So, we have two equal sides and one equal angle
The triangles are equal through SSA (side , side, angle)
