The golden ratio in a circle


Symmetry festival 2019

Center for Art and Media Karlsruhe

Lorenzstraße 19, 76135 Karlsruhe, Germany

July 24 - 28, 2019

 
 
Abstract

We will discuss some features of the golden section in connection to some basic figures together with their circumcircle like the equilateral triangle, the cross consisting of five squares, and, of course, the regular pentagon. Some examples lead to fractals through iteration. Other examples are based on circles with the golden ratio as radius.
