triangle PQR is congruent to triangle PSR by the SSS congruence property So because corresponding parts of a triangle are congruent, we know that angle SRP is congruent to angle QRP. This shows us that angle SRQ has been bisected. The same can be said about angle SPQ Repeat this whole process for the other two interior triangles to show that the other two angles are also bisected.
