OA = OB, OC = OD, Angle AOB = Angle COD. Prove that AC=BD
Dear Student,
Please find below the solution to the asked query:
Given : AOB = COD --- ( 1 )
And
COB = COB --- ( 2 ) ( Same angles )
So, If we subtract equation 2 in equation 1 we get :
AOB - COB = COD - COB
We know " Euclid's third Axiom: If equals be subtracted from equals, the remainders are equal. " we get :
AOC = BOD --- ( 3 )
In AOC and BOD
OA = OB ( Given )
AOC = BOD ( From equation 3 )
And
OC = OD ( Given )
Thus ,
AOC BOD ( By SAS rule )
Therefore,
AC = BD ( By CPCT ) ( Hence proved )
Hope this information will clear your doubts about topic.
