Right triangle and "b" are the legs of the triangle. If the incircle is tangent to the hypotenuse AB at point P, then denoting the semi-perimeter as "s", we have and , and the area is given by This formula only applies to right triangles. If an altitude is drawn from the vertex with the right angle to the hypotenuse then the triangle is divided into two smaller triangles which are both similar to the original and therefore similar to each other. From this: In equations, where "a", "b", "c", "d", "e", "f" are as shown in the diagram. Thus Moreover, the
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
