Right triangle two legs (the two sides that meet at a right angle). This can be stated in equation form as where "c" is the length of the hypotenuse, and "a" and "b" are the lengths of the remaining two sides. Pythagorean triples are integer values of "a, b, c" satisfying this equation. The radius of the incircle of a right triangle with legs "a" and "b" and hypotenuse "c" is The radius of the circumcircle is half the length of the hypotenuse, Thus the sum of the circumradius and the inradius is half the sum of the legs: One of 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
