# What is secent of a circle?

Secant: In geometry what is secent of a circle, lets see.

Circle means a closed figure, such as a circle or ellipse. Secant means a line that cuts off a circle at a point where two sides meet. In mathematics, secants are lines that cut off a circle into two smaller circles. The word’secant’ comes from Latin (secare) meaning ‘to cut’.

A secant is a line that cuts off some part of a circle into two parts. For example, the diameter of a circle divides the circle into two equal parts. This is called a tangential division.

## Where did the term Secant come from?

In geometry, secant means perpendicular to another line segment. The concept was originally derived from the Greek word sekundos meaning “one after another.” Secant was once used to describe the angle between two lines or angles, but now has broader usage. For example, if you take two points on a sphere (or other curved surface), then the distance between those two points is called the secant.

### What is the definition of secant of a circle? How is it calculated?

The word “secant” means “to cut off at an angle”. In geometry, the term refers to the line segment from a point on a curve to another point on the same curve. This is also known as the tangent line (or tangent) or perpendicular line (perpendicular).
Secants are often used to describe the slope of a line between two points on a curve. They are important in calculating areas and volumes of curves.
