Right triangle a right triangle. For a given angle, a right triangle may be constructed with this angle, and the sides labeled opposite, adjacent and hypotenuse with reference to this angle according to the definitions above. These ratios of the sides do not depend on the particular right triangle chosen, but only on the given angle, since all triangles constructed this way are similar. If, for a given angle α, the opposite side, adjacent side and hypotenuse are labeled "O", "A" and "H" respectively, then the trigonometric functions are For the expression of hyperbolic functions as ratio of the sides of a
St Michael and All Angels Church, Southwick is shaped like a right-angled triangle whose longest side runs from north to south. Shoreham Harbour and the English Channel form the southern boundary; the eastern side corresponds with the ancient boundary between the Rapes of Bramber and Lewes (now the boundary between Adur district and the city of Brighton and Hove, and also between West Sussex and East Sussex); and the western boundary was created in 1848 when Kingston Lane was built to form the eastern limit of Kingston Buci parish. Until 2008, there were two other active Anglican churches in the parish, both of which were administered from
