Question

In the below figure, write all pairs of adjacent angles and all the linear pairs.

Answer 1

From figure, pairs of adjacent angles are :

(∠AOC, ∠COB) ; (∠AOD, ∠BOD) ; (∠AOD, ∠COD) ; (∠BOC, ∠COD)

And Linear pair of angles are (∠AOD, ∠BOD) and (∠AOC, ∠BOC).

[As ∠AOD + ∠BOD = 180° and ∠AOC+ ∠BOC = 180°.]
