Question

diagonals PR and SQ of the rectangle pqrs bisect each other at 0 angle ROS =120, then angle PQS =
​

Answer 1

Answer:

To find ∠PQO and ∠PSQ.

PQRS is a rectangle, and O is the intersection point of diagonals PR and SQ.

PR=SQ [Diagonals of rectangle are equal]

PO=Qo [Diagonals of rectangle bisect each other]

∴∠PQO=∠OPQ→(1) [Angles opposite to equal sides]

In △POQ ,

∠PQO+∠POQ+∠OPQ=180

∘

2∠PQO+110

∘

=180

∘

[From (1)]

∠PQO=

Now, in △PQS

∠PQS+∠QPS+∠PSQ=180

∘

35

∘

+90

∘

+∠PSQ=180

∘

∠PSQ=180

∘

−125

∘

=55
