Part of the Arizona Technology Council. An arithmagon is a polygon with numbers at its vertices which determine the numbers written on its edges. An introduction to arithmagons can be found here. Usually, we add the numbers at the vertices to find the numbers on the edges, but these arithmagons follow a different rule. Can you work out how the values at the vertices determine the values on the edges in the arithmagons generated by the interactivity below? If you are given the values on the edges, can you find a way to work out what values belong at the vertices?
