In the given figure, two lines \(\overleftrightarrow{AD}\) and \(\overleftrightarrow{EC}\) intersects at O. Name two pairs of vertically opposite angles in the given figure.

Answer»

In the given figure, two lines \(\overleftrightarrow{AD}\) and \(\overleftrightarrow{EC}\) intersecting at O.

∠AOE = ∠COD (Vertically opposite angles)

∠1 = ∠3

∠EOD = ∠AOC (Vertically opposite angles)

∠EOD = ∠AOB + ∠BOC (we know ∠AOC = ∠AOB + ∠BOC)

∠2 = ∠5 + ∠4
