Answer 1

Answer:

Step-by-step explanation:

Given,

∠4 = 110°

∠7 = 65°

In the figure,

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

If m║n, then sum of co-interior angles should be 180°.

⇒ ∠4 + ∠5 = 180°

⇒ 110 + 65 = 180

However, 175° ≠ 180°.

Therefore, m∦n because sum of co-interior angles is not 180°.
