The Four Color Theorem

WebIn mathematics, the four color theorem, or the four color map theorem, states that no more than four colors are required to color the regions of any map so that no two adjacent regions have the same color. Adjacent means that two regions share a common boundary curve segment, not merely a corner where three or more regions meet. It was the first … WebA theorem that says: When you try to color in a map so that no two touching areas have the same color, then you only need four colors. (Note: some restrictions apply).
