Chord (geometry) Geometric line segment whose endpoints both lie on the curve. Common lines and line segments on a circle, including a chord in blue. A chord (from the Latin chorda, meaning "bowstring") of a circle is a straight line segment whose endpoints both lie on a circular arc. If a chord were to be extended infinitely on both directions ...
Formula of Chord of Circle. There are two basic formulas to find the length of the chord of a circle: Chord length using perpendicular distance from the center = 2 × √ (r 2 − d 2). Let us see the proof and derivation of this formula. In the circle given below, radius 'r' is the hypotenuse of the triangle that is formed.
Chord circle theorems are geometrical properties of circles that can be calculated using the chord of a circle. The chord of a circle is a line segment that connects two points that sit on the edge of a circle. The longest chord in a circle is the diameter of the circle. Recall the parts of a circle that are essential to understand circle chord ...

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. The figure below depicts a circle and its chord. In the given circle with ‘O’ as the center, AB represents the diamet...
There are two basic formulas to find the length of the chord of a circle which are: Where, 1. r is the radius of the circle 2. c is the angle subtended at the center by the chord 3. d is the perpendicular distance from the chord to the circle center
Example 1: A chord of a circle is equal to its radius. Find the angle subtended by this chord at a point in the major segment. Solution: Let O be the centre, and AB be the chord of the circle. So, OA and OB be the radii. Given that chord of a circle is equal to the radius. AB = OA = OB Thus, ΔOAB is an equilateral triangle. That means ∠AOB = ∠OBA =...

Practice chord of a circle questions. 1. A, B, C A,B, C and D D are points on a circle with centre O O. BD B D is the diameter and AC AC is a chord that is perpendicular to the diameter at E E. BE = 2cm BE = 2cm and CDE = 30^ {\circ} C DE = 30∘. Calculate the length of x x, the distance between C C and E E. 4cm 4cm.
The line segment joining any two points on a circle’s circumference is known as the chord of a circle. The longest chord of a circle passes through the center of the circle. This chord is what we know as the diameter. In the figure below, $\overline {PQ}$, $\overline {RS}$, and $\overline {TU}$ are chords of the circle.

A chord of a circle is a straight line segment whose endpoints both lie on the circle. A secant line, or just secant, is the line that intersects two points on a curve. More generally, a chord is an intersection of an internal Tangent line and an external Secant line. In this blog post, we will explore chords of a circle in more depth and detail.
