General Idea
Trigonometry is essentially the study of triangles. Some concepts are widely known and maybe learned in middle school or even geometry classes. Two examples are the 180-degree rule and the "Pythagorean Theorem". These two rules are the basis for which all calculations are based and should be used as a reference.
