Answer 2

$\huge\underbrace{Concept}$

Sum of adjacent angles in a parrlelogram is 180°

Opposite angles are parrlel and equal

$\huge\underbrace{Solution}$

Hence given that two adjacent angles are equal

So,one angle be x

Other angle be y

Hence x = y

They are adjacent angles sum should be 180°

So, x + y = 180°

We know x=y

So, x + x = 180°

2x = 180°

x = 90°

So, y = 90°

Required angles are 90° ,90°

$\huge\underbrace{Verification:}$

Sum should be 180°

So angles are 90°,90°

Sum 90°+90°=180° Hence verified

Hence two adjacent angles are equal and makes an angle 90° We call it as a rectangle
