A magic polygon is a polygonal
magic graph with
integer
An integer is the number zero (), a positive natural number (, , , etc.) or a negative integer with a minus sign ( −1, −2, −3, etc.). The negative numbers are the additive inverses of the corresponding positive numbers. In the language ...

Perimeter magic polygon
A magic polygon, also called a perimeter magic polygon,
is a
polygon
In geometry, a polygon () is a plane figure that is described by a finite number of straight line segments connected to form a closed '' polygonal chain'' (or ''polygonal circuit''). The bounded plane region, the bounding circuit, or the two t ...
with an integers on its sides that all add up to a
magic constant
The magic constant or magic sum of a magic square is the sum of numbers in any row, column, or diagonal of the magic square. For example, the magic square shown below has a magic constant of 15. For a normal magic square of order ''n'' – that is ...
. It is where positive integers (from 1 to ''N'') on a ''k''-sided polygon add up to a constant.
Magic polygons are a
generalization
A generalization is a form of abstraction whereby common properties of specific instances are formulated as general concepts or claims. Generalizations posit the existence of a domain or set of elements, as well as one or more common character ...

magic triangles.
Magic polygon with a center point
Victoria Jakicic and Rachelle Bouchat defined magic polygons as ''n''-sided regular polygons with 2''n''+1 nodes such that the sum of the three nodes are equal. In their definition, a 3 × 3 magic square can be viewed as a magic 4-gon. There are no magic odd-gons with this definition.
Magic polygons and degenerated magic polygons
Danniel Dias Augusto 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.

In recreational mathematics, a square array of numbers, usually positive integers, is called a magic square if the sums of the numbers in each row, each column, and both main diagonals are the same. The 'order' of the magic square is the number ...
