Question

Do ∠COE and ∠EOD form a linear pair? (ii) Are ∠BOD and ∠DOA supplementary? (iii) Is ∠1 vertically opposite angle to ∠4? (iv) Which is the vertically opposite angle of ∠5?​

Answer 1

Answer:

Solution 9

i): Yes ∠1 and ∠2 are adjacent angles.

ii): No, ∠AOC is not adjacent to ∠AOE [OC and OE do not lie on either side of common arm OA]

iii): Yes, ∠COE and ∠EOD form a linear pair of angles

iv): Yes, ∠BOD and ∠DOA are supplementary. [ + = 180]

v): Yes, ∠1 is vertically opposite to ∠4

vi): Vertically opposite angle of ∠5 is ∠2 +∠3 i.e ∠BOC
