Ex 5.2, 6 In the given figures below, decide whether l is parallel to m (ii)For lines l and n ∠3 = ∠ 1 ∠ 3= 75° Now, for lines l and m, with transversal n. ∠2 & ∠3 are interior angles on same side of transversal. And their sum is ∠2 + ∠3 = 75° + 75° = 150° ≠ 180° As sum of interior angles on the same side of transversal is not 180° Line l and m are not parallel.
