4-Color Theorem with Polygons
Instructions: Use the slider corresponding to each polygon to change the color of the polygon. See if you can create a map where no two regions with a common boundary share the same color.
Questions to think about:
1. How can you color this map so that no two adjacent regions share the same color?
2. Is it possible to color the map using fewer than four colors? Why or why not?
3. Why in the real world might it be useful to color adjacent regions differently, using as few of colors as possible?
