## NCERT Solutions for Class 10 Maths Chapter 8: Important Topics

The word trigonometry is derived from the Greek words ‘tri’ (meaning three), ‘gon’ (meaning sides), and ‘metron’ (meaning measure). Trigonometry is the study of relationships between the sides and angles of a triangle. Today, most of the technologically advanced methods used in Engineering and Physical Sciences are based on trigonometric concepts. This branch of Mathematics, called Trigonometry, is extremely helpful in dealing with height and distances, which are not easy to measure.

In this article, we have provided NCERT Solutions for Class 10 Maths Chapter 8 which will help students understand the topics, complete their in-text exercises, and work on their doubts. Before delving further into the details, students can refer to the important topics that are included in NCERT 10th Maths Chapter 8 Introduction to Trigonometry in the table below:
