Circles and secants
WebThe secant of a circle is the line that cuts across the circle intersecting the circle at two distinct points. The difference between a chord and a secant is that a chord is a line … WebA straight line can intersect a circle at zero, one, or two points. A line with intersections at two points is called a secant line, at one point a tangent line and at no points an exterior line. A chord is the line segment that joins two distinct points of a circle.
