Chord (geometry) 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 infinite line extension of a chord. 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. Every diameter is a chord, but not every chord is a diameter. The word chord is from the Latin chorda meaning bowstring.
Arc Length. Definition: The distance along the curved line making up the arc. (See also Angle measure of an arc .). Try this Drag one of the orange dots that define the endpoints of the blue arc. The arc length will be continuously calculated. The arc length is the measure of the distance along the curved line making up the arc. It is longer than the straight line distance between its endpoints (which would be a chord). There is a shorthand way of writing the length of an arc: This is read as The length of the arc AB is 10.
