Perpendicular Bisector of a Chord Conjecture


The cord of a circle is a segment whose endpoints are on the circle. This conjecture states that the perpendicular bisector of any chord passes through the center of the circle. This could give us a good way to find the center of any circle!

The precise statement of the conjecture is:

Conjecture (Perpendicular Bisector of a Chord ): The perpendicular bisector of a chord in a circle passes through the center of the circle.
