Proof: perpendicular … The definition of a chord is a group of musical notes, usually three or more notes, played together to create harmony. The musical notes A, C and E played together simultaneously is an example of a chord. The chord definition states that the degree of curve is the angle formed by two radii drawn from the center of the circle (point O, figure 3) to the ends of a chord 100 feet or 30.48 meters long. 11 chapters | (Unequal Chords Theorem). OM = OL. Tangent: Radius is always perpendicular to the tangent at the point where it touches the circle. A chord of a circle is a straight line segment whose endpoints both lie on a circular arc.

In the circle shown, PQ and AB are chords with their endpoints P, Q and A, B respectively lying on the circle. d is the perpendicular distance of the center of the circle to the chord. The diameter that passes through the center of the circle is the longest chord of the circle. Chord length is, therefore, the straight line distance between two points on the curve. More generally, a chord is a line segment joining two points on any curve, for instance, an ellipse. A chord of a circle is a line that connects two points on a circle's circumference. Since we know the length of the chord and the perpendicular distance between the chord and the center of the circle, we can find the radius of the circle using the equation L = 2sqrt(r2 - d2) with L = 5 and d = 2. A chord is the line segment that joins two different points of the circle which can also pass through the centre of the circle. A chord is a segment connecting two points on a circle.
