Special right triangle than 256: Isosceles right-angled triangles cannot have sides with integer values, because the ratio of the hypotenuse to either other side is , but cannot be expressed as a ratio of two integers. However, infinitely many "almost-isosceles" right triangles do exist. These are right-angled triangles with integral sides for which the lengths of the non-hypotenuse edges differ by one. Such almost-isosceles right-angled triangles can be obtained recursively, "a" is length of hypotenuse, "n" = 1, 2, 3, ... Equivalently, where {"x", "y"} are the solutions to the Pell equation , with the hypotenuse "y" being the odd terms of the
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. "Sheh-see", emphasis on first syllable), which uses the fut. aff. conjugation of "seas". The Scots Gàidhlig variant is Seasaidh/Teasaidh/Teasag, (pronounced "Cheh-say"). Jessie (given name) Jessie is a given name in its own right, but may also be a
