Question

In the adjacent figure, a line n falls on lines l and m such that the sum of the interior angles 1 and 2 is less than 180°, then what can you say about lines l and m.

Answer 1

they will intersect at one point when they are produced in the direction of given interior angles.

Answer 2

Answer:

l and m are non-parallel lines.

Step-by-step explanation:

In the adjacent figure, a line n falls on lines l and m such that the sum of the interior angles 1 and 2 is less than 180°.

We have to tell about the nature of lines l and m

Here, line n is a transversal line which intersect both the lines l and m

∠1 and ∠2 are co-interior angles and if the lines are parallel then their sum will be equal to 180°. Bot it is given that sum of the interior angles 1 and 2 is less than 180°

⇒ lines are not parallel.

Hence, l and m are non-parallel lines.
