Fermat's right triangle theorem is, by the Pythagorean theorem, they would form two integer-sided right triangles in which the pair formula_10 gives one leg and the hypotenuse of the smaller triangle and the same pair also forms the two legs of the larger triangle. But if (as Fibonacci asserted) no square congruum can exist, then there can be no two integer right triangles that share two sides in this way. Because the congrua are exactly the numbers that are four times the area of a Pythagorean triangle, and multiplication by four does not change whether a number is square, the existence of a square
Jessie (given name) are Jane/Joan (Sìne), Janie (Sìneag), and Janet/Janice (Seònaid); though spelling may change slightly dependent upon the form of Gaelic (Irish or Scottish). An additional nickname for Jessie, heard in Scotland, is Jinty (or Jinny), a connection to Jean (female given name)/Jane/Jennie. Jessie is as an Anglicisation of the Gaelic root-word of "seas", meaning "to stand". In Irish Gaelige this is Seasaidh/Seasaídh (pro.
