Circle Chord Formulas
A line segment whose two end points lie on the circumference of a circle is referred to as a chord of the circle. Circle chord formulas can be found on a number of websites, including: http://en.wikipedia.org. Most involve other trigonomic theorem's such as the power of a point theorem (AP·PB = CP·PD). Chord functions and formulas are the basis of ancient trigonometry, whereas sine functions are the basis of modern trigonometry.
