A secant line intersects two or more points on a curve (From the Latin secare "cut or sever") They are lines, so extend in both directions infinitely Circle On a circle they look like this: Theorems There are three theorems of interest here: Intersecting Secants Theorem Intersecting Chords Theorem Angle of Intersecting Secants Theorem

A secant is a line that intersects a curve at a minimum of two different points The secant line above cuts (intersects) the curve at three distinct points In Geometry, secant lines are often used in the context of circles The secant line below, in red, intersects the circle with center O, twice
