Special right triangle : , which follows immediately from the Pythagorean theorem. Of all right triangles, the 45°–45°–90° degree triangle has the smallest ratio of the hypotenuse to the sum of the legs, namely . Of all right triangles, the 45°–45°–90° degree triangle has the greatest ratio of the altitude from the hypotenuse to the sum of the legs, namely . Triangles with these angles are the only possible right triangles that are also isosceles triangles in Euclidean geometry. However, in spherical geometry and hyperbolic geometry, there are infinitely many different shapes of right isosceles triangles. This is a triangle whose three angles
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
