### Introduction to Trigonometry: Summary

The word trigonometry is derived from the Greek words ‘tri’ (meaning three), ‘gon’ (meaning sides), and ‘metron’ (meaning measure). Trigonometry is the study of relationships between the sides and angles of a triangle. Long ago, ancient Greek and Indian astronomers used these handy techniques to measure the distances of stars and planets from the Earth very precisely. Even today, most of the technologically advanced methods used in Engineering and Physical Sciences are based on trigonometrical concepts. This branch of Mathematics, called Trigonometry, is extremely helpful in dealing with height and distances, which are not easy to measure.

This chapter will first study the ratios of sides of a right triangle concerning its acute angles and see how these ratios only depend on the measure of the angles involved. You will then go through the names and definitions of these six trigonometric ratios of an angle. You will also define the value of these trigonometric ratios for standard angles, including 0° and 90°. At last, you will also establish some relationships among these trigonometric ratios termed trigonometric identities.
