Answer:
Step-by-step explanation:
1). Two angles are said to be linear pair if they are adjacent angles formed by two intersecting lines. A linear pair of angles must add up to 180°.
2). Two angles are adjacent when they have a common side and a common vertex and don't overlap.
~~~~~~~~~~~~
(i). 1 pair is ∠AOC and ∠BOD, another one pair is ∠AOD and ∠BOC ;
(ii). Linear pairs: 1) ∠DOB and ∠BOC 2) ∠BOC and ∠COA
I would add three pairs more, despite the fact that ∠AOD is divided by ray OE.
So, it will be ∠AOD and ∠DOB , ∠AOD and ∠COA , ∠COE and ∠EOD ;
(iii) Pairs of adjacent angles: 1) ∠AOE and EOD , 2) ∠AOE and ∠COA, 3) ∠EOD and ∠DOB , 4) ∠DOB and ∠BOC .
