Question

in the given figure, if x+y=w+z, then prove AOB is a line ​

Answer 1

Answer:

we know that ( x+y)+(w+z)=360⁰(complete angle)

and x+y=w+z

(x+y)+(x+y)=360⁰

2(x+y)=360

x+y=180⁰

so x and y is supplementary to each other

and we know that angle of 180⁰ is a straight line

and we see that x+y is angles between AB

so AB=180⁰

so it is a straight line

hence proved
