Right Triangular Angle and Side Calculator
This calculator rerquires the use of a Javascipt enabled Web Browser. This calculator is designed to give the two unknown factors in a right triangle, assuming two factors are known. This calculator is for a right triangle only! The factors are the lengths of the sides and one of the two angles, other than the right angle. All values should be a positive value, but decimals are allowed. Fill in two and only two values then click on Calculate. If you enter more than two the calculator will not work. The two other modifiable values will be filled in, along with the angle 3 field. In a triangle, all interior angles total to 180 degrees. No two angles can total to 180 degrees or more. Angle C is always 90 degrees; angle 3 is either angle B or angle A, whichever one is NOT entered. You are not able to modify the the units entered into the angles 3 or angle c fields. These will be calculated by the program.
