The Word 'trigonometry' is derived from the Greek words “Trigonometria” meaning “Triangle

measuring” In fact trigonometry is the study of relationship between the sides and angles of the triangle.

In This chapter, we will study some ration of the sides of a right triangle with respect to its acute angles,

called trigonometric ratios of the angle. We will restrict our discussion to acute angle only. However, these

ratios can be extended to other angles also. We will also define the trigonometric rations for angles of

measure 0^o and 90^o. We will calculate trigonometric ratios for some specific angles and establish some

identities involving these rations, called trigonometric identities. do solve Trigonometry questions.
