Question:
In the below fig. transversal t intersects two lines m and n, ∠4 = 110° and ∠7 = 65° is m ∥ n?
Solution:
Given:
∠4 = 110° and ∠7 = 65°
To find: is m ∥ n
Here ∠7 = ∠5 = 65° [Vertically opposite angle]
Now. ∠4 + ∠5 = 110 + 65 = 175°
Therefore, m is not parallel to n as the pair of co interior angles is not supplementary.
