nonagon with a dot in the center and all other dots
Kaynak: Centered nonagonal numbertransformations to "cheat," creating figures impossible to construct under the traditional compass-and-straight-edge rules (such as the regular
nonagon ).
Kaynak: The Geometer's SketchpadA Descartes snark is obtained from the Petersen graph by replacing each vertex with a
nonagon and each edge with a particular graph

nonagon decagon regular decagon hendecagon dodecagon hexadecagon icosagon swastika
Kaynak: List of geometric shapesThe two partizans, nine sides of the
nonagon and circular center allude to the numerical designation (2-9-0) of the unit. Subordinate Units
