Secants - Concept

Concept Concept (1)

A secant is a line, ray, or line segment that intersects a circle in two places. Three points are covered: (1) secants that intersect in a circle which divide each other proportionally, (2) the angle formed by secants which intersects in a circle and is half the sum of the intercepted arcs, and (3) two secants drawn from the same point outside a circle that form an angle whose measure is half the difference of the intercepted arcs.
