Nonagon, Another animation of an approximate construction[edit]

Hi Jalexbnbl,
Thank you for your interest in this construction.

Unfortunately, in your construction is a mistake.

The auxiliary line g is not perpendicular to w_4!

The auxiliary line g aims over the point O to the point N (virtually a ruler at the points O and N applied), between O and N, therefore no auxiliary line. Thus, the circular arc MON is freely accessible for the later intersection point R.

The description of the construction was not formulated clearly. I've changed it!
