Or how about this one? Here’s the steps for constructing a regular dodecagon – a twelve-sided figure, together with my solution.
Not bad for a first try. Is this a standard geometry curriculum anywhere, any more??
1. Draw a line AB.
2. Arcs AB and BA
3. Arc radius AB, center O
4. Circle center O-AB
5. Arcs radius OA, centers E, A, B, F.
6. Repeat arcs radius OA on new intersections.
7. Complete the figure.
You try it. Let me know if it works as well for you as it did for me.
