Chord Of A Circle
Chord of a circle
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.
How do you find the chord of a circle?
If the radius and the distance of the center of the circle to the chord are given, the chord of the circle can be calculated. We just need to apply the chord length formula: Chord length = 2√(r2-d2), where 'r' is the radius of the circle and 'd' is the perpendicular distance from the center of the circle to the chord.
What is the formula of chord?
| r | It is the radius of the circle. |
|---|---|
| \theta | It is the angle made at the centre by the chord under consideration |
Is a radius a chord?
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.
What is chord and radius?
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. The chord of a circle which passes through the centre of the circle is called the diameter of the circle.
What is the example of chord?
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 a chord in math?

- By Roman numeral e.g. I or i.
- By technical name e.g. “dominant” or “diminished supertonic”.
What is difference between chord and diameter?
The chord-The chord is described as a line segment that joins any two points in the circle. The diameter- Chord, which passes through the center of the circle, is called the diameter of the circle. It is the longest chord a circle could have.
Is radius half of a chord?
Finding the Length of a Chord Approximate your answer to the nearest mm. Using the formula, half of the chord length should be the radius of the circle times the sine of half the angle.
