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.

Wouldn't an infinite-sided polygon be more like a circle than a straight line? Of course the angle at any given vertex between two adjacent sides would still essentially be 180º.
