## What is the meaning of chord?

A line segment connecting two points on a curve. Example: the line segment connecting two points on a circle’s circumference is a chord. When the chord passes through the center of a circle it is called the diameter.

## What is the formula of chord?

The formula for the chord length is: 2rsin(theta/2) where r is the radius of the circle and theta is the angle from the centre of the circle to the two points of the chord.

## What is the meaning of chord in circle?

A chord of a circle is a straight line segment whose endpoints both lie on a circular arc. The infinite line extension of a chord is a secant line, or just secant. More generally, a chord is a line segment joining two points on any curve, for instance, an ellipse.

## Is a radius a chord?

Any segment which connects two different points on a circle is a chord. The radius of a circle connects the centre and one point on the circle. Hence a radius cannot be called a chord.

## Can a chord be two notes?

A chord, simply, is any combination of three or more notes. While two notes is technically harmony, they are not considered chords. Theoretically, any combination of notes is a chord, however, when used in a certain combination, some notes complement each other better than others.

## Which line is called as chord?

In plane geometry, a chord is the line segment joining two points on a curve. The term is often used to describe a line segment whose ends lie on a circle. The term is also used in graph theory, where a cycle chord of a graph cycle is an edge not in whose endpoints lie in.

## What are the properties of chord?

Chord Property. The perpendicular from the centre of a circle to a chord bisects the chord. In the figure below, the line through the centre of the circle and the chord of the circle are perpendicular. As a result, the chord is bisected by the line.

## What is a chord length?

A chord is a line segment connecting any two points on the circumference of a circle. You can also calculate chord length if you know both the radius and the length of the right bisector, which is the distance from the center of the circle to the center of the chord.

## What is sector of a circle with example?

To recall, a sector is a portion of a circle enclosed between its two radii and the arc adjoining them. For example, a pizza slice is an example of a sector representing a fraction of the pizza.

## Why is diameter the longest chord?

The diameter of a circle is considered to be the longest chord because it joins to points on the circumference of a circle. In the circle below, AB, CD, and EF are the chords of the circle. Chord CD is the diameter of the circle.

## Is a chord a diameter?

A segment of a straight line joining two points on a circle is called a chord; a chord that passes through the center of the circle is called a diameter. (Ambiguously, the word ” diameter ” also denotes the length of a diameter.)

## How is a radius named?

It has two points on the outside edge of the circle. Write the name of each circle, radius, and diameter. A circle is named by the point in the center. A radius is a line segment from the center of the circle to the edge.

## What is the relationship between a chord and a radius?

The radius of a circle is any line segment connecting the centre of the circle to any point on the circle. The chord of a circle is a line segment joining any two points on the circle.

## How many chords are there in a circle?

Answer. 2 chords divide a circle into 4 regions.
