Question

in figure if X + Y is equal to w + Z then prove that A or B is a line​

Answer 1

Answer:

Step-by-step explanation:

x+y=180                (linear pair)

w+z=180               (linear pair)

x+y make a straight angle,i.e., 180

so, ab 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______❤
