[edit] Summary
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 completed the full circle.
