A chord is a line segment joining two distinct points on a curve, usually a circle.^{[1][2]} An apothem is a line segment extended from the bisector of the chord to the center of the circle.^{[2] page 110} A sagitta extends from the bisector of the chord to the edge of the circle in the same line as the apothem. Any angle whose vertex is on the circle and whose legs pass through the end points of the chord is a subtended angle of the chord.^{[3]} The arc cut off by the chord is called the arc of the chord.
