How to Construct a Golden Spiral In Geoebra
The golden spiral is a visual representation of Phi (1.6).
Using geogebra, we can first use our tools to create a square and then save this square as a tool to use later. From here we can then create the shell that the spiral falls in, making sure the ratio of the boxes always falls in a 2:1 ratio. Then using the arc tool we are able to build a spiral starting with the smallest boxes first and following through to the corner of the biggest box. The ratio of the arcs approaches phi and can be continued to higher numbers of the Fibonacci sequence.
