Question

IN THE GIVEN FIG . IF X+Y =W+Z , THEN PROVE THAT AOB IS A LINE.

Answer 1

h ello dear I think that u have forget to send image
but I know the answer
9th class.na
I that figure x+y=w+z (given)
and x+y+w+z= 360°(complete angle)
x+y+x+y=360°( x+y=w+z)
2(x+y)=360
x+y=360/2
x+y=180°
since the angle on aob is 180
so aob is a line
thank u friend

Answer 2

x+y=w+z
x+y+w+z=360
x+y+x+y=360
2(x+y)=360
x+y=360/2
×+y=180


if angle sum is 180 then it is line
