Question 4 In the given figure, if lines PQ and RS intersect at point T, such that PRT = 40 , RPT = 95 and TSQ = 75 , find SQT. In PRT By angle sum property of triangle PRT + RPT + PTR = 180 90 + 45 + PTR = 180 135 + PTR = 180 PTR = 180 135 PTR = 45 Also, STQ = PTR STQ = 45 In SQT By angle sum property of triangle SQT + STQ + TSQ = 180 SQT + 75 + 45 = 180 SQT + 120 = 180 SQT = 180 120 SQT = 60
