PQRS is a rectangle and its diagonal PR and QS intersect at O.if angle POQ=110 find the measure of

- angle PQO
- angle PSQ
- angle ORS

P S

Q R

PQRS is a rectangle in which O is the intersection point of both the diagonals PR and QS

We have angle POQ= 110®

Now we need to find out , anglePQO and angle PSQ

As we know in rectangle both the diagonals are equal

So, PR = QS

Also diagonals bisect each other

So PO = QO

Hence, anglePQO = angleOPQ ……………1

Now in triangle POQ ,

AnglePQO + anglePOQ + angleOPQ = 180®

anglePQO + 110 + anglePQOc = 180 (from eqn 1)

2 anglePQO = 180-110

anglePQO = 70/2 = 35®

now , in triangle PQS

anglePQS + angleQPS +anglePSQ = 180

35 + 90 + anglePSQ = 180

125 + anglePSQ = 180

anglePSQ = 180-125 = 55® ans
