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. The chord of a circle which passes through the centre of the circle is called the diameter of the circle. The diameter of a circle is the distance across a circle. The diameter is also the longest chord of a circle.

Are the radius and diameter chords?
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. The chord of a circle which passes through the centre of the circle is called the diameter of the circle.
Is a radii a chord?
Answer: As discussed above, any line segment which connects two points on the circumference of the circle is known as a chord. While a radius connects the centre of the circle with a point of a circle. Therefore, from the definition of both terms, we can state that radius is not a chord.
Do diameters count as chords?
(a) Yes, every diameter of a circle is also a chord because a chord of a circle is any line segment joining two points on the circumference of the circle.
Why is a radius not 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.
What are chords in a circle?
Chord of a Circle Definition The chord of a circle can be defined as the line segment joining any two points on the circumference of the circle. It should be noted that the diameter is the longest chord of a circle which passes through the center of the circle.
What is a chord but not a diameter?
A diameter satisfies the definition of a chord, however, a chord is not necessarily a diameter. This is because every diameter passes through the center of a circle, but some chords do not pass through the center. Thus, it can be stated, every diameter is a chord, but not every chord is a diameter.
How many chords are in a circle?
4 chords can be drawn in a circle.....)
Is diameter the longest chord?
The Longest chord of any circle is its diameter. Therefore, the diameter of a circle is twice the radius of it.
What makes up a chord?
A chord is a combination of three or more notes. Chords are built off of a single note, called the root. In this lesson, we will discuss triads. They are created with a root, third, and fifth.
What's a chord in geometry?
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.
Is a secant always a chord?
A straight line that intersects a circle in two points is called a secant line. A chord is the line segment that joins two distinct points of the circle. A chord is in a unique secant line and every secant line defines a unique chord. In geometry, a secant is a line that cuts any curve in at least two different points.
How many chords are in a circle?

What is the circle with the center O?
If centre of a circle is point O, the circle would be named circle O or the circle with centre O. Definitions. 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.
What is a chord in math?
Chord: Chord of a circle is a line joining any two points on the circumference of the circle. It does not have to pass through the center of the circle.
What are the points on the circumference of a circle?
The two given points on the circumference of the circle are {eq}D {/eq} and {eq}E {/eq}. The line that connects them is the chord of the circle.
