For example, an area of a right triangle is equal to 28 in² and b = 9 in. Our right triangle side and angle calculator displays missing sides and angles! Now we know that: a =

If the angle is between the given sides, you can directly use the law of cosines to find the unknown third side, and then use the formulas above to find the missing angles, e.g. given a,b,γ: calculate c = a 2 + b 2 − 2 a b × cos ( γ ) c

This calculator calculates for the length of one side of a right triangle given the length of the other two sides. A right triangle has two sides perpendicular to each other. Sides a and b are the
