I have created two ordinary well-known rangOlis with strings.
Why with strings? The lines have no thickness. Therefore if one draws rangOlis
with lines, then the third dimension is lacking. So mirror reflections are quite
common. But since strings have thickness, these types of symmetries are eliminated.
We get only pure rotational symmetries in the rangOlis. In each of the given rangOlis,
there are two strings that interweave. One can see these alternately going up
and down. Since I used nylon material, the strings are taut and I have to use
cellophane tape so that the strings follow the pattern drawn on paper.
