Three regular polygons, all with unit sides, share a common vertex and are all coplanar. Each polygon has a different number of sides, and each polygon shares a side with the other two; there are no gaps or overlaps. Find the number of sides for each polygon. There are multiple answers.

re(2): solution by Thalamus)
I would say that the locus of points on the infinitesided polygon was coextensive with a straight line, as is a circle of infinite radius, and diameter as 2*aleph1 is still aleph1. The diagonal of the infinitesided polygon is also infinite. So the set of points is identical.
