Find out three linear pairs from the figure.
In the figure (IMAGE)
(a) Is ∠1
adjacent to ∠2?
(b) Is ∠AOC adjacent to ∠AOE?
(c) Do ∠COE and ∠EOD from linear pair?
(d) Are ∠BOD and ∠DOAsupplementary?
(e) is ∠1 vertically opposite to ∠4?
(f) What is the vertically opposite angle of ∠5?
In the given figure, if ∠AOC and ∠BOC are in ratio 2 : 3, find ∠AOC, ∠COB, ∠BOD and ∠AOD.
