Q12 of 22 Page 70

Let’s write how are the line segment OA and OE situated in the figure beside.


∠EOD = 24°

∠DOC = 81°


∠COB = 55°


∠BOA = 20°


∠EOD + ∠DOC + ∠COB + ∠BOA


24° + 81° + 55° + 20° = 180°


Since, sum of all the angles is 180° it means that EOA is a straight line.


Thus, line segments OA and OE forms a straight line.
