Perpendicular From Centre to Chord
Perpendicular from centre of a circle bisects the chord.
Line segment joining the centre of a circle to the midpoint of a chord is perpendicular to the chord.
The perpendicular bisectors of two chords of a circle intersect at its centre.
There is one and only one circle which passes through 3 non-collinear points.
