Answer 2

Step-by-step explanation:

$\huge{\boxed{\underline{\mathcal{\purple{Ans}\green{wer}}}}}$

In the figure, we know that it is a parallelogram.

So, the adjacent sides have a difference of 180° between them.

Now , According to question,

We have to prove <POQ=90°

First we will look at triangle POQ.

Here angle P AND Q have been bisected .

So,

1/2P+1/2Q=90°{half of 180°}______________________(1)

Now,

1/2P+1/2Q+O=180°

Now, From (1)

We have

90°+O=180°

So, O=90°

Hence PROVED.
