They also learn how to use the Pythagorean theorem to solve problems involving right triangles.Įxercise 8.3 - In this exercise, students learn about complementary angles and how to find the trigonometric ratios of complementary angles. Students learn how to use trigonometric ratios to find the height and distance of an object, as well as the angle of elevation and depression. The exercise also covers the concept of trigonometric identities, which are fundamental relationships between trigonometric functions.Įxercise 8.2 - This exercise deals with the application of trigonometric ratios to solve real-life problems. They learn how to find the values of these ratios for acute angles in a right triangle. Below is a brief explanation of each exercise:Įxercise 8.1 - In this exercise, students are introduced to the basic trigonometric ratios - sine, cosine, and tangent, and their reciprocal functions. NCERT Solutions for Class 10 Maths Chapter 8 'Introduction to Trigonometry' contains four exercises.
