Question

16 In the given figure, PQ = PR and angle APR = 110°. Find the measure of angle PQR and angle QPR. A P. B. Q R.​

Answer 1

Answer:

If we consider AP and BR as parallel lines and when

PR is a transversal We know that <APR & <PRQ are supplementary

So <PRQ= 180-110 = 70

Since PQR is a isosceles ∆

<PQR and <PRQ will be equal

We know sum of all angles of a triangle is 180

So <QPR= 180-(70+70) =180-140=40
