A user has requested this calculator for the instances where the 3-4-5 method just doesn't work. This calculator will give you the hypotenuse of a triangle. Input the length of 2 sides of a triangle, in feet, and the calculator will output the 3rd side (hypotenuse) in decimal feet. This of course only works for a right triangle. This can be helpful when pulling square for concrete forms, walls, or floor and roof sheathing.
