alleryA line drawn through the centre of a circle to bisect a chord is
AA tangent
BParallel to the chord
CCoincident with another diameter
DPerpendicular to the chord
Answer & Solution
Correct answer: D. Perpendicular to the chord
1. The line from centre to midpoint of a chord is perpendicular to that chord.
2. This is a standard converse of the chord-bisector theorem.
3. Hence option A.
