Question

from the figure tell which pair of lines are parallel and why explain the reason

Answer 1

Answer:

Line l is parellel to line m.

Step-by-step explanation:

This is because 120 + 60 = 180

Also, 100 + 80 = 180

Since,they are co - interior angles, the lines L and M are parallel.

Answer 2

Answer: l is parallel to m

Step-by-step explanation:because

80°+100°=180 - eq1

and these two angels are on the same side of traversal .so there sum should be equall to 180°

And from eq1 we can conclude that these two lines are parallel

Therefore l ||m
