The following is the calculation formula for the length of the hypotenuse of a rightangled triangle, based on the Pythagorean theorem where c is the length of the hypotenuse, and a and b are the lengths of the other two sidesA 90 degree triangle is defined as a triangle with a right angle or in other words a ninety degree angle Given any known side length of a 90 degree triangle and one other value (another side, angle, area value, etc), one can find all unknown values of the same 90 degree triangle To find the area of such triangle, use the basic triangle area formula is area = base * height / 2 In our case, one leg is a base and the other is the height, as there is a right angle between them So the area of 45 45 90 triangles is `area = a² / 2` To calculate the perimeter, simply add all 45 45 90 triangle sides
