Question

Q3. In the given figure, two straight lines AB and CD intersect each other at O such that angle AOC =620. Find the measure of <AOD,

angle BOD.​

Answer 1

Given : -

Line AB intersects line CD at point O,

Angle AOC = 62°

To find : -

1. Angle AOD
2. Angle BOD

Solution : -

Angle AOC + Angle AOD = 180° ......... ( Angles in a linear pair )

62° + Angle AOD =180°

Angle AOD = 180° - 62°

Angle AOD = 118°

Angle AOC = Angle BOD ........... ( vertically opposite angles )

Angle BOD = 62°
