Answer:

OD BC [A line drawn through the centre of a circle bisecting a chord is to the chord]

In rt. OBD and OCD

OB = OC (radii)

OD = OD (common)

ODB = ODC [each 90o]

(The angle subtended by an arc at the centre is double the angle subtended by it at any point on the remaining part of the circle.)

From (i) and (ii)

BOD = A
