Answer 1

Answer:

ABllDC,

Angle ABD=Angle BDC----(alternate interior angles)

Angle BAC= Angle ACD-----(alternate interior angles

In triangles AOB and COD

Angle ABD= Angle BDC-----(proved above )

Angle BAC= Angle ACD-----(proved above )

Angle AOB= Angle COD----(vertically opposite angles)

Therefore triangle AOB is congruent to triangle COD.

AO=CO------(by CPCT)

BO=DO----(by CPCT)
