WebGiven a circle and an arc on the circle, the chord is the line that subtends the arc. A chord's perpendicular bisector passes through the center of the circle and bisects the angle. One half of the bisected chord is the sine of one half the bisected angle, that is, [12] and consequently the sine function is also known as the half-chord. WebClassifying triangles.
