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."
