Answer 2

Answer:

Step-by-step explanation:

We know that,

x+y+w+z=360°( sum of all angles round a point is equal to 360°)

(x+y)+(w+z)=360° {given that x+y= w+z}

2(x+y) =360°

x+y=180°

Since,

W+z=x+y

w+z=180°

Now, x+y=180° and w+z=180°

From axiom 6.2 ............

•°• AOB IS A STRAIGHT LINE
