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.

${\large{\underbrace{\underline{\bf{Answer:-}}}}}$

According to the figure, line 'n' is a transversal line which intersect both the lines 'l' and 'm'.

If line 'l' is parellel to line 'm', then ∠1 and ∠2 will be co-interior angles whose sum would be 180°.

Given, that sum of ∠1 and ∠2 is less than 180°.

∴ Lines are not parellel.

Hope this helps uh! ♡

Answer 2

Answer:

If line 'l' is parellel to line 'm', then ∠1 and ∠2 will be co-interior angles whose sum would be 180°.

• Given, that sum of ∠1 and ∠2 is less than 180°.

∴ Lines are not parellel.
