Question

In the given figure, y= 108 and x= 72 . are the lines m || n? justify?
​

Answer 1

In such figure if The sum of x and y is 180 than the lines are parallel.

As interior angle property says if line are parallel than some of co interior Angles will be 180

hence if we measure the angles it will be

108°+72°= 180°

The final result is that Yes the lines are parallel

Answer 2

Interior angles are equal to 180 degrees, so by the given condition m and n are parallel lines
