# Constructing The Nonagon Using Only Compass & Square

NEW DISCOVERY (7/13/21): The Nonagon (9-sided polygon) using only a Compass and Square with no measurements. The Leonard Da Vinci Construction box has yielded us the precise proportions of the Regular Nonagon which was previously proven to be an 'Impossible task' using only compass and straight edge by Gauss and Wantzel in the 19th Century. Now their proof is no longer valid with this proof that we will be submitting for publication by someone who lived three hundred years before them: Leonardo Da Vinci. This now makes the fourth (7,9,11, and 13 -polygon) non Fermat Prime Polygon whose compass and straight edge construction was purportedly proven impossible by Gauss and Wantzel Theorem
