Line AB is a straight line. At point B, a ray BC is drawn such that ∠ABC=35∘. Another ray BD is drawn on the side of BC opposite to A so that ∠CBD=65∘. Answer the following questions with reasons.
(i) List all the pairs of adjacent angles formed at point B.
(ii) For each pair named in part (i), state whether the pair is a linear pair. Give a reason for your answer.
(iii) Decide whether any two angles in the figure are complementary. Justify your conclusion.
