Full Answer

Trigonometry is a branch of mathematics that studies the relationships between the lengths and angles of a triangle. In the third century B.C., Greek mathematicians, such as Euclid and Archimedes, studied the properties of angles in circles, proved theorems and wrote formulas that are still equivalent to the formulas used in 2014.

Trigonometry states that the three angles of any triangle always add up to 180 degrees. Once the angles of the triangle are found, the ratio of its sides may be determined with the help of the trigonometric functions sine, cosine and tangent.
