In this chapter, students will understand the concept of the line of sight and learn to define angle of elevation and angle of depression. These concepts explain how angles are formed when an observer looks up or down at an object.

Using trigonometric ratios, students will solve real-life problems related to heights and distances, such as finding the height of buildings or the depth of wells. This chapter enhances practical problem-solving skills and highlights the real-world applications of trigonometry, making it an important part of the CBSE curriculum.
