Answer:
ans
Step-by-step explanation:
(i) 106∘+64∘=170∘
Since sum of co-interior angles is not 180∘
Therefore given lines are not parallel
(ii) Alternate interior angles of 75∘=180∘−75∘=105∘
Since alternate interior angles are not equal
Therefore, given lines are not parallel
(iii) Corresponding angle of 57∘=180∘−123∘=57∘
i.e Corresponding angles are equal
Therefore given lines are parallel
