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 into a line, the object is a secant line. The perpendicular line passing through the chord's midpoint is called sagitta (Latin for "arrow").
A chord is any line segment whose endpoints lie on a circle. The diameter is a special kind of chord that passes through the center of a circle. It is also the longest possible chord for a given circle. In the diagram above, line segment AB and CD are both chords.
What is the Chord of a Circle in Mathematics? The chord of a circle refers to a straight line joining two points on the circumference of the circle. The longest chord in a circle is its diameter which passes through its center. How to Find the Chord of Circle?

A chord is a lot like a secant, but where the secant is a line stretching to infinity in both directions, a chord is a line segment that only covers the part inside the circle. A chord that passes through the center of the circle is also a diameter of the circle.
圓上弦和弧的性質 包括有: 等弦對等弧(equal chords, equal arcs)、等弧對等弦 (equal arcs, equal chords)、等弦至圓心等距 (equal chords , equidistant from centre)、與圓心等距的弦相等 (chords equidistant from centre are equal)。
2024年7月13日 · 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 C is an edge not in C whose
2023年11月21日 · This lesson introduces the chord of a circle in math. Learn how to draw a chord, and study its properties, theorems, and ways to calculate its length.
What is a Chord? Answer: : A chord is a line segment that joins any two points on a circle. Diagram 1. In other words, a chord is basically any line segment starting one one side of a circle, like point A in diagram 2 below, and ending on another side of the circle, like point B. Points A and B are the endpoints of chord AB .
By definition, a chord is a straight line joining 2 points on the circumference of a circle. 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. Properties of a Chord.
