Glad you found this and show that it is possible with simple tools to divide a circle into five sections. I was looking at this page “The Golden Rectangle and the Golden Ratio” and in particular addendum 1 and 3. Addendum 3 made me see how easy it is to create the square root of 5.

I did have to use the line tool in order to get the one half distances in two places. Once I got P1 and P2, I used the triangle made up of the center, P1, and P2 in order to find the other points. This required the Transform tool in order to place into position but degree readouts are not needed.
