1.	In Fig, transversal l intersects two lines m and n, ∠4 = 110° and ∠7 = 65°. Is m \|\| n?
Answer» Given, ∠4 = 110°, ∠7 = 65° To find: m ‖ n Here, ∠7 = ∠5 = 65°(Vertically opposite angle) Now, ∠4 + ∠5 = 110° + 65° = 175° Therefore, m is parallel to n as the pair of co interior angles is not supplementary.

In Fig, transversal l intersects two lines m and n, ∠4 = 110° and ∠7 = 65°. Is m || n?

Answer»

Given,

∠4 = 110°,

∠7 = 65°

To find: m ‖ n

Here,

∠7 = ∠5 = 65°(Vertically opposite angle)

Now,

∠4 + ∠5 = 110° + 65°

= 175°

Therefore,

m is parallel to n as the pair of co interior angles is not supplementary.
