Dear Student,

  
In //gm ABCD, AC and BD are diagonals of parallelogram

PROVE:OA=OC & OB=OD

ABCD is a parallelogram ,therefore

AB//DC and AD//BC

in triangle AOB and COD

 

AB=CD(opp sides of parallelogram are equal)

 

therefore triangle AOBtriangleCOD(ASA congurence criterian)

OA=OC & OB=OD(cpct)

hence, prove that diangonals of parallelogram bisect each other.
