One of the most important applications of trigonometry is solving triangles. To solve a triangle is to find the measures of all six parts of the triangle: the three sides and the three angles.
Often in a real life situation only a few parts are given. Trigonometric functions can be used to solve both right and oblique triangles when the measures of only two or three parts are given. The following lessons will discuss how to solve right triangles and how to apply this knowledge to situations in real life.
