Question

in the given figure,if angle a=angle b then prove that line |ll line m​

Answer 1

Answer:

angle a = angle b ( alternate exterior angles)

as the alternate angles are equal then the line on whin these angles are formed are parallel

Hence proved

I hope it will help you

Answer 2

Step-by-step explanation:

Thier opposite angles are equal. (Vertically opposite)

a'=b'

Therefore, interior opposite angles are equal.

Thereby, lines are parallel by theorem. (If interior opposite angles are equal then lines are parallel)
