@hartificial.de Danke ... das halt geklappt. Und ich habe das Projekt schon online ...

Zur Visualisierung des Distributiv-Gesetzes ... das ging wesentlich einfacher, als es in #GeoGebra zu erstellen. Gemini hat mir die ganzen Möglichkeiten schnell mal abgenommen.

Using Geogebra to model the geometry needed for six interlocking pentagonal prisms

One post for the five-pointed star

Having made 6- and 8-pointed stars, the next step was to make 3- to 7-pointed stars.

I eventually found the required proportions after more experimenting in Geogebra. For a short edge of 1 unit, the long edge needs to be 3.73, 2.41, 2.0, 1.73 and 1.6 for 3- to 7-points.

Odd numbers of units are awkward for choosing colours: either every unit a different colour or use 2 or 3 colours.

As the number of units goes up and beyond 10, the folded locking flap becomes tiny and almost useless.

Eight-pointed star folded from eight 3:2 rectangles.

A similar folding method as before, but I had to model the unit in Geogebra to find that the required proportion was 3:2.
