Näherungsonstruktion
- Die Methode ähnelt der des Dreizehnecks
Ergebnis
Bezogen auf den Einheitskreis r = 1 [LE]
- Konstruierte Seite des Neunzehnecks in GeoGebra
- Seite des Neunzehnecks
- Absoluter Fehler der konstruierten Seitenlänge
- Konstruierter Zentriwinkel des Neunzehnecks in GeoGebra
- Zentriwinkel des Neunzehnecks
- Absoluter Fehler des konstruierten Zentriwinkels
Beispiel um den Fehler zu verdeutlichen
Bei einem Radius r = 1 Mrd. km (das Licht bräuchte für diese Strecke ca. 56 min) wäre der absolute Fehler der konstruierten Seitenlänge ca. 0,21 mm.

Enneadecagon, animation approximate construction with 15 s pause
Approximate construction
- The method is similar to that of the Tridecagon
Score
Based on the unit circle r = 1 [unit of length]
- Constructed side length of the enneadecagon in GeoGebra
- Side length of the enneadecagon
- Absolute error of the constructed side length
- Constructed central angle of the enneadecagon in GeoGebra
- Central angle of the enneadecagon
- Absolute error of the constructed central angle
Example to illustrate the error
At a radius r = 1 billion km (the light would need about 56 min for this distance) the absolute error of the side length constructed would be approx. 0.21 mm.
