Circle chord geometry
A chord 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. More generally, a chord is a line segment joining two points on any curve, for instance, an ellipse. A chord that passes through a circle's center point is the circle's diameter. The word chord is from the Latin c… WebCircle worksheets, videos, tutorials and formulas involving arcs, chords, area, angles, secants and more.

WebJun 15, 2024 · 1. Chord Theorem #1: In the same circle or congruent circles, minor arcs are congruent if and only if their corresponding chords are congruent. Figure 6.12.1. In both of these pictures, ¯ BE ≅ ¯ CD and ^ BE ≅ ^ CD. 2. Chord Theorem #2: The perpendicular bisector of a chord is also a diameter. Figure 6.12.2. WebFeb 7, 2024 · Write down the chord length formula: c = 2 · √ (r² - d²). Here: r is the radius; c is the chord's length; and. d is the chord's distance to the circle's center. Replace r and d with their respective values. The result will be the length of any chord at that distance from the circle's center.
