A perpendicular from the center of a circle to a chord is a line segment that intersects the chord at a single point. The length of this segment is called the radius of the circle.
Perpendiculars from the center to a chord divide the circle into two arcs. The arc that is below the chord is called the first arc, and the arc that is above the chord is called the second arc.
The distance from the center of the circle to any point on the chord is called the chord length. The distance from the center of the circle to any point on the perpendicular from the center to the chord is called the perpendicular distance.
The perpendicular from the center to the chord is always perpendicular to the chord and is equal in length to the radius of the circle.
Here are some examples:
The perpendicular from the center of a circle to the chord of a circle is always perpendicular to the chord.
The perpendicular distance from the center of a circle to the chord of a circle is equal to the radius of the circle.
If the chord is a diameter of the circle, the perpendicular from the center of the circle to the chord will bisect the circle
