Question

ANYBODY WHO SOLVES THIS FIRST WILL BE MARKED AS THE BRAINLEIST??:)

Answer 1

Given,

Angle AOC= Angle ACO
Angle BOD= Angle BDO.


We now Angle BOD= Angle AOC (Opposite Angles are equal)

Hence,

Angle AOC = Angle ACO= Angle BOD= Angle BDO.


Now Angle ACO= Angle BDO (from above)

Hence they are the interior alternat angles & they are equal. Hence the line AC & line BD are parallel and AB and DC acts as transverse lines.



Hope this helps.

Mark as brainliest if it was useful.
