Summary
| Description |
Equilateral chord of a circle. The earliest trigonometry was based on chords of a circle. A chord of length equal to the radius made a natural base quantity for measuring angles. Using the standard Babylonian sexagesimal divisions, one sixtieth of this defined a degree; while six such chords complete the circle. |
