+67

∘

=173

∘

Since sum of co-interior angles is not 180

∘

Therefore given lines l and m are not parallel.

(ii) Alternate interior angle of 75

∘

=180

∘

−75

∘

=105

∘

Since alternate interior angles are not equal

Therefore, given lines l and m are not parallel.

(iii) Corresponding angle of 57

∘

=180

∘

−123

∘

=57

∘

Since, the corresponding angles are equal

Therefore the given lines l and m are parallel
