Question

Tell me this answer with full explaination..........

​

Answer 1

$it \: is \: given \: that \: x + y = w + \\ also \: we \: know \: that \: all \: angles \: drawn \: from \: a \: single \: point \: when \: added \: give \: the \: answer \: as \: 360 \: degree. \\ therefore \: x + y + w + z \: = 360 \\ x + y + x + y = 360 \\ 2x + 2y = 360 \\ x + y = 180 \\ therefore \: ab \: is \: asraight \: line$

Answer 2

Given:x+y=w+z

therefore, it forms a full circle

therefore,x+y+w+z = 360°

therefore,x+y=180°, and w+z=180°

Now,

we have to prove that AOB is a line.

AOB is a line because it contains angle, w and angle z

which is 180°.

Therefore, AOB is a line, line is always of 180° .

hope it proves helpful to you.......★★★★
