Question

If angle 1=50° and angle 2=130°, prove that l||m.​

Answer 1

${\huge{\underline{\underline{\mathfrak{\green{Solution:-}}}}}}$

the adjacent angle of angle 50 degree is 130

IE. 180-50=130 (due to st. angle)

so, angle 2ie. 130degree is equal to adjacent angle of 50 degree by alternate or corresponding angle

and Lllm. proved!

Answer 2

Answer:

one is an acute angle  and two is an obtuse and if you add them together you get a straight line.
