What is a chord?

Hint: In a circle with centre O , any line joining two points of the circle is called the chord. A chord of a circle is a straight line segment whose endpoints both lie on the circle.

Complete step-by-step answer:
Step 1:
Let's consider a circle with centre O.

Step-2
Now let's draw a line AB joining any two points of the circle

And this line AB is called the chord of the circle.

Therefore , a line joining any two points of the circle is known as the chord of the circles.


Note: Some of the properties of the chord are
1.Chords are equidistant from the centre if and only if their lengths are equal.
2.Equal chords are subtended by equal angles from the centre of the circle.
3.A chord that passes through the centre of a circle is called a diameter and is the longest chord.
