Out of 80 marks (combined) for Class 10 CBSE Maths, 12 marks are assigned to Chapter 8, "Trigonometry." The paper is divided into four sections. Each section has a different set of marks, with 1 mark, 2 marks, 3 marks, and 4 marks assigned to the questions. This chapter will most likely include at least 2-3 mandatory questions. The main topics covered in this chapter are as follows:
The Beginning: In previous classes, you've already learned about triangles, specifically right triangles. In this chapter, we'll look at some trigonometric ratios of the angle, ratios of the sides of a right triangle to their acute angles. Also defined are the trigonometric ratios for angles of measure 0^{o} and 90^{o}.
We'll calculate trigonometric ratios for some specific angles and establish trigonometric identities, which are identities involving these ratios.
Identities Trigonometric: In previous classes, you learned about the concept of ratio. Certain ratios involving the sides of a right triangle are now referred to as trigonometric ratios. Using various Trigonometry functions, the topic is explained with appropriate examples.

Some Specific Angles' Trigonometric Ratios: You're already familiar with constructing angles of 30^{o}, 45^{o}, 60^{o}, and 90^{o} from Geometry. The values of the trigonometric ratios for these angles and 0^{o} will be found in this section. It uses appropriate examples to explain 45^{o}, 30^{o}, and 60^{o} trigonometric ratios and 0^{o} and 90^{o} trigonometric ratios.
Complementary Angle Trigonometric Ratios: When the sum of two angles equals 90 degrees, they are said to be complementary. Various formulas for solving numerical problems involving trigonometric ratios are discussed in this topic.
Identities Trigonometric: You may recall that when an equation is true for all values of the variables involved, it is called an identity. Similarly, if an equation involving trigonometric ratios of an angle is true for all values of the angles involved, it is called a trigonometric identity. We will prove one trigonometric identity in this section and then use it to prove other useful trigonometric identities.
Conclusion: The conclusion is a condensed version of the concepts that includes all of the key points that you'll need to remember to solve numerical problems related to the chapter.
