## What is a Secant of a Circle?

A secant of a circle is a line that intersects a circle in two points.

## Secant of a Circle Definition

The secant of a circle is a line that intersects a circle at two points. The secant line is perpendicular to the radius at the point of intersection.

## Difference Between Secant and Chord:

A chord is a straight line segment that connects two points on a curve. A chord is always shorter than the radius of the circle.

A secant is a line that intersects a curve at two points. A secant is always longer than the radius of the circle.

## Difference Between Secant and Tangent:

The secant and tangent are two types of lines that intersect a curve at a single point. The secant is a line that intersects a curve at two points, while the tangent is a line that intersects a curve at just one point. The difference between the secant and tangent is that the secant is a line that intersects a curve at two points, while the tangent is a line that intersects a curve at just one point.

## Secant of a Circle Formula

The secant of a circle is a line segment that intersects a circle at two points. The formula for the secant of a circle is:

## The Theorem of Secants of a Circle

The theorem states that the secant of a circle is always perpendicular to the radius drawn to the point of intersection.
