The line joining the centre of a circle to the midpoint of a chord is perpendicular to the chord.

(Converse of Theorem 3) The line joining the centre of a circle to the mid-point of a chord is perpendicular to the chord.

Theorem 10.4 : The line drawn through the centre of a circle to bisect a chord is perpendicular to the chord.

Theorem :-2The perpendicular from centre of a circle to the chord bisects the chord and Perpendicular bisectors of two chords of a circle intersects at the centre.

The perpendicular from the centre of a circle to a chord bisects the chord.

The perpendicular from the centre of a circle to a chord bisects the chord.

If two equal chords of a circle in intersect within the circle,prove that : the segments of the chord are equal to the corresponding segments of the other chord.the line joining the point of intersection to the centre makes equal angles with the chords.
