Question

In the given figure, PQ = PR and PRQ=70. Find QAR.


  1. 40

  2. 140

  3. 80

  4. 70


Solution

The correct option is A

40


In ΔPQR

PQ = PR       (Given)

PQR=PRQ=70        [Base angles of an isosceles triangle are equal]

So, QPR=180(70+70)=40

Also, QAR=QPR              [Angles in the same segment are equal].
QAR=40
