In any box-shaped room, two adjoining sides, such as the floor and a wall or two adjoining walls, form two sides of a right-angle triangle making a 90° angle between them. It would be preferable, however, to have methods that we can apply directly to non-right triangles without first having to create right triangles. The program must check it it's a right angled triangle. Right Angled Triangle 'Right Angled Triangle' is a triangle with one internal angle equal to 90 degrees (right angle). Triangle having one angle of measure 90 degree is called Right angle Triangle. The 5x is the hypotenuse and 5x -2 is the base and 3x +1.
