Summary
| Description |
English: This file was created to show what is described at File:Equilateral chord.svg: "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." |
