Question

x+y=w+z then prove that AOB IS A LINE

Answer 1

(x+y)+(w+z)=360°
x+y=w+z (given)
(x+y)+(x+y)=360°
2(x+y)=360°
x+y=180°
Thus AOB is a straight line

Answer 2

☺ Hello mate__ ❤

◾◾here is your answer...

Given:  x+y=w+z             (1)

To prove: AOB is a line

Proof:    x+y+w+z=360°       (Sum of all angles around point=360°)

Putting (1) in the above equation, we get

x+y+x+y=360°

⇒2x+2y=360°

⇒x+y=360°/2=180°

Therefore, x and y form a linear pair

Hence, AOB is a straight line.

I hope, this will help you.

Thank you______❤
