Magic triangle (mathematics)

From HandWiki

A magic triangle (also called a perimeter magic triangle[1]) is an arrangement of the integers from 1 to n on the sides of a triangle with the same number of integers on each side, called the order of the triangle, so that the sum of integers on each side is a constant, the magic sum of the triangle.[1][2][3][4] Unlike magic squares, there are different magic sums for magic triangles of the same order.[1] Any magic triangle has a complementary triangle obtained by replacing each integer x in the triangle with 1 + nx.[1]

Examples

Order-3 magic triangles

Order-3 magic triangles are the simplest (except for trivial magic triangles of order 1).[1]
