11. [-/10 Points] DETAILS FAPP10 20.1.007. MY NOTES ASK YOUR TEACHER In addition to the vertex types of regular polygons with at most 12 sides, exactly five others are possible, each involving one polygon with more than 12 sides. None of these vertex types leads to a semiregular tiling. The five many-sided polygons involved in these five vertex types have 15, 18, 20, 24, and 42 sides. Determine the other polygons in each of these five vertex types. (Denote the other two polygons in each vertex type by number of sides, and enter these values starting with the smallest number of sides.) .20 OOOOC . 24 1.42 12.
