Answer:
CB = Diameter of the circle.
OD is perpendicular to AB.
Therefore, AD = DB
AC and AB are chords of the circle. So, they will be equal.
AC = AB
OD //AC,
By theorem mid point theorem,
AC = 2 OD.

Answer:
Proved below.
Bohot mehnat lagi, isliye brainliest mark kardena.
Step-by-step explanation:
Since, BC is diameter therefore O is midpoint
Since, OD is perpendicular to AB, therefore D is midpoint of AB because perpendicular drawn from centre of the circle bisects the chord.
Therefore, In Triangle ABC,
O and D are midpoints of BC and AB
Therefore OD is half of AC(according to Mid Point Theorem)
OD=1/2AC
THEREFORE, 2OD=AC
AC=2OD
hence proved.
