kindly give solution to the question in the image. Asked by bhvyajot | 17 Oct, 2018, 11:03: AM Expert Answer
Consider angle PRQ = x
so PQR = x ......iso triangle
angle QPR = 180 - 2x
now, for QT || to PR
we need to prove
angle PQT = angle QPR
lets consider this is equal
angle PQT = angle QPR = angle SQT= 180 - 2x
now,
angle PQT + angle SQT + angle PQR = 180....angles in st. line
180-2x + 180 - 2x + x = 180
so, x= 60
that means triangle PQR should be equilateral, so data is missing in the question
