उत्तर
It is given that,∠ABC is on circumference of circle BD is passing through centre.
Construction: Join A and C to form AC and extend BO to D such that BD be the perpendicular bisector of AC.
Now in \[\bigtriangleup BDA \text{ and } \bigtriangleup BDC\] we have
AD = CD (BD is the perpendicular bisector)
So ,
