Question

in the given figure,if x+y=w+z,then prove that AOBis a line.​

Answer 1

Answer:

...........................

Answer 2

x+y+w+z = 360 (360° formed at a point)

Given x+y=w+z

x+y+w+z = 360

(x+y)+ (x+y) = 360°

2(x+y) = 360°.

then, x+y =360/2 = 180°

since ,Angle AOB = 180°

........................

Hence,AOB is a line .
