# NCERT Solutions Class 10 Maths Chapter 8 Exercise 8.2 Introduction to Trigonometry

NCERT solutions for class 10 maths chapter 8 exercise 8.2 Introduction to Trigonometry now moves on to elaborating the values of the trigonometric ratios of some specific angles. There are five angles that are under consideration, that is, 0°, 30°, 45°, 60°, and 90°. Students learn how to use these trigonometric ratios with respect to these particular angles. In order to solve this exercise kids must remember the value of trigonometric ratios of the different angles. NCERT solutions class 10 maths chapter 8 exercise 8.2 is a short exercise with just 4 questions. These are in different formats, such as tick the correct answer, word problem, true and false, and evaluation sums. By attempting these problems kids get an understanding of why the value of a trigonometric ratio is given by that specific number.

The main point to remember while solving this exercise is that kids need to make a chart with all the values of the trigonometric ratios and keep it handy while revising these sums. A fun fact to note is that as the angle increases from 0° to 90°, sin A increases from 0 to 1, and cos A decreases from 1 to 0.
