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
Borough of Wokingham closest higher education provider is the main Whiteknights Park campus of the University of Reading immediately north-west. Elevations range between 30 and 70 metres above sea level except higher in about 5% of the borough. The highest is an escarpment containing parts of the rural and wooded northern area, the hinterland of three Thames-side villages, facing the 30-mile long Chilterns AONB, west and north. A geological part of that range of hills, Bowsey Hill reaches 137m, in Wargrave civil parish, from the river. Approximately a right-angled triangle, the borough is long north to south. It uses as its longest edge
