A secant is a line that intersects a circle at exactly two points. If two chords intersect a circle, then the products of the lengths of the chord segments are equal. If two secants intersect in the exterior of a circle, then the product of the measures of one secant segment and it’s external secant segment is equal to the product of the measures of the other secant and it’s external secant segment.
