What is the meaning of trigonometry?
The word trigonometry comes from two Greek words, trigonon, meaning triangle, and metria, meaning measurement. This is the branch of mathematics that deals with the ratios between the sides of right triangles with reference to either of its acute angles and enables you to use this information to find unknown sides or angles of any triangle. Trigonometry is not just an intellectual exercise, but has uses in the fields of engineering, surveying, navigation, archicecture, and even rocket science.
