Question

in the give figure line segment A B and C D intersect at O prove the vertically opposite angle format are equal​

Answer 1

Step-by-step explanation:

given :SegAB and segCD intersect at O

To prove:angle AOD =angle COB

contertion:Draw a line SQ such that line SQ parallel to CD and extant line AB till point E,lineEB intersect line SQ

proof:angleAOD=angleSAO......alternate angle....(1)

angleSAO=angleCOB.....coresponding angle..... (2)

by (1)and(2)

angleAOD=angleCOB

Hence prove
