Solution of Right Triangles

If any two sides of any right-angled triangle are known, the third side can

and "a" and "b" are the other sides.

An easier method for the solution of the sides of a right triangle, and one

which also includes the solution of the angles, is found in the use of

trigonometric functions. The parts of a triangle consist of three sides and

three angles. A right triangle may be solved if, in addition to the right
