Consider the ΔPQR. PRS is the exterior angle and QPR and PQR are interior angles. So, PRS = QPR+PQR (According to triangle property) Or, PRS -PQR = QPR ———–(i) Now, consider the ΔQRT, TRS = TQR+QTR Or, QTR = TRS-TQR We know that QT and RT bisect PQR and PRS respectively. So, PRS = 2 TRS and PQR = 2TQR Now, QTR = ½ PRS – ½PQR Or, QTR = ½ (PRS -PQR) From (i) we know that PRS -PQR = QPR...
