Chord properties geometry
The chord function is defined geometrically as shown in the picture. The chord of an angle is the length of the chord between two points on a unit circle separated by that central angle. The angle θ is taken in the positive sense and must lie in the interval 0 < θ ≤ π (radian measure). See more 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 … See more The midpoints of a set of parallel chords of a conic are collinear (midpoint theorem for conics).

Chords are equidistant from the center if and only if their lengths are equal. 2. Equal chords are … See more Chords were used extensively in the early development of trigonometry. The first known trigonometric table, compiled by Hipparchus, tabulated the value of the chord function for every 7+1/2 degrees. In the second century AD, Ptolemy of Alexandria … See more WebAngle and chord properties Many of the angle and chord properties of circles are inter-related and the order of treatment becomes important. For example, from the theorem 'the angle at the centre is twice the angle at the circumference standing on the same chord' comes the theorem 'angles in the same segment are equal'.
