Question

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

Answer 1

Answer:

proved

Step-by-step explanation:

x + y + w + z = 360degrees

2(y + x) =360deg.

y + x = 180 deg.

angle AOB = 180deg.

so AOB is str. line

Answer 2

Answer:

x+y+w+z = 360⁰(complete angle)

w+z+w+z = 360⁰

2(w+z) = 360⁰

w+z =180⁰

sum of w and z angle is equal to 180⁰

then hence, proved AOB is a line
