Question

i want my question answer​

Answer 1

Answer:

if two lines i.e ab and cd intersect each other.they have two pair of opposite angles

i.e

angleAOC , angleDOB , angleAOB, angleCOB

to prove -angleAOC = angle DOB and angleAOD=angle COB

proof-

angleAOC + angleAOD =180⁰ linear pair_1

angleAOD + angleBOD=180⁰ linear pair_2

angleAOC + angleAOD = angleAOD + angleBOD

i.e angleAOC = angleBOD

similarly, (angleAOD = angleCOB) HENCE PROVED

Answer 2
