What is Golden angle?
[[File:Golden_Angle.svg|link=https://en.wikipedia.org/wiki/File:Golden_Angle.svg|right|thumb|The golden angle is the angle subtended by the smaller (red) arc when two arcs that make up a circle are in the [[golden ratio]]]] In [[Geometry]], the '''golden angle''' is the smaller of the two [[Angle|angles]] created by sectioning the circumference of a circle according to the [[golden ratio]] into two [[Curve|arcs]]. according to algebra, let ''a+b'' be the circumference of a [[circle]], divided into a longer arc of length ''a'' and a smaller arc of length ''b'' such that: : <math> rac{a + b}{a} = rac{a}{b} </math> The golden angle is then the angle subtended by the smaller arc of length ''b''.
