Question

14. In the given figure AO = BO and ∠A=∠B.


(i) Is ∠AOC=∠BOD? Why?


(ii) Is ∆ AOC≅∆ BOD? If yes, by which congruence

condition?



(iii) State the three facts you have used to answer (ii).


(iv) Is ∠ACO=∠BDO? Why?


​

Answer 1

Explanation:

1) yes aoc = bod because ther vertically opposite angles

2) they are congruent by ASA criteria

4) yes aco = bdo because they are alternate interior angles of a transversal
