Magic polygon

A magic polygon is a polygonal magic graph with integers on its vertices.

Not to be confused with Polygon Magic.

perimeter magic polygon

A magic polygon also called a perimeter magic polygon[1][2] is a polygon with an integers on its sides that all add up to a magic sum.[3][4] It is where positive integers (from 1 to N) on a k-sided polygon add up to a constant, or magic sum.[1] Magic polygons are the generalization of other magic shapes[5] such as magic triangles.[6]

This displays order 3 magic triangles, a type of magic polygon.

magic polygon with a center point

Victoria Jakicic and Rachelle Bouchat defined the magic polygon as an n-sidef regular polygons with 2n+1 nodes that the sum of the three nodes are equal. In their definition, 3×3 magic square can be viewed as a magic 4-gon. There are no magic odd-gon in this definition.[7]

Magic Polygons and Degenerated Magic Polygons

Danielle Dias Augustoa and Josimar da Silva defined the magic polygon P(n,k) as a set of vertices of concentric n-gon and a center point. In this definition, Magic polygons of Victoria Jakicic and Rachelle Bouchat can be viewed as P(n,2) magic polygons. They also defined degenerated magic polygons[8]
