Question

In parallelogram ABCD, bisectors of angles A and B intersect each other at O, the value of ∠AOB is

Answer 1

Answer:

90▪︎ is right answer according to me

Answer 2

Answer:

Property no 4 : Adjacent angles are supplementary .

Thus,

Angle( A +B) =180°

let A and Bbe x ,x = 2x=180°

x=90°

Bisector of A and B= 45 °45°

ATQ

: A+B+O=180°

: 45°+45°+O=180°

:90°+O=180°

:O=180°-90°

:O =90°.

Glad I could help you.

Thanks.
