Step-by-step explanation:
since AB and AC are two both chords then we can say AB = AC..........eq(1)
now
OD is perpendicular to AB
and bisect AB
so
OD=1/2AB
or
2OD = AB
AB = AC(from 1)
hence
AC= 2OD or CA=2OD

Answer:
Perpendicular from the centre of a circle to a chord bisects the chord
We know that OB⊥AB
From the figure we know that D is the midpoint of AB
We get
AD=BD
We also know that O is the midpoint of BC
OC=OB
Consider △ABC
Using the midpoint theorem
We get OB∥AC and
OD=
2
1
×AC
By cross multiplication
AC=2×OD
Therefore, it is proved that AC∥DO and AC=2×OD
