NCERT Solutions Class 10 Maths Chapter 8 Introduction to Trigonometry 

The word ‘trigonometry’ is derived from the Greek words ‘tri’ (meaning three), ‘gon’ (meaning sides) and ‘metron’ (meaning measure). In fact, trigonometry is the study of relationships between the sides and angles of a triangle. The earliest known work on trigonometry was recorded in Egypt and Babylon. Early astronomers used it to find out the distances of the stars and planets from the Earth. Even today, most of the technologically advanced methods used in Engineering and Physical Sciences are based on trigonometric concepts

The Introduction to Trigonometry Class 10th chapter introduces the basic trigonometric ratios-sine, cosine, and tangent-based on right-angled triangles. Through NCERT Class 10 Maths Textbook Solutions, students will easily find the step-by-step solution for all problems present in the NCERT textbook so that they can study how to solve those problems accurately. Class 10 Maths Chapter 8 Solutions are designed to strengthen students' conceptual understanding and problem-solving skills, ensuring better preparation for exams.

2.0What Will Students Learn in Chapter 8: Introduction to Geometry?

  • In Maths Class 10 Introduction To Trigonometry chapter, you will study some ratios of the sides of a right triangle with respect to its acute angles, called trigonometric ratios of the angle.
  • Students will also learn about the relationships between these ratios and how to apply them to solve various problems involving angles and sides of triangles
  • Discussions will be restricted to acute angles only. However, these ratios can be extended to other angles also.
  • You will also define the trigonometric ratios for angles of measure 0° and 90°.
  • Calculate trigonometric ratios for some specific angles and establish some identities involving these ratios, called trigonometric identities.

Frequently Asked Questions

Trigonometry is a mathematical discipline focused on the exploration of relationships between angles and sides in a right triangle. Trigonometry is necessary for solving problems involving distances and angles in right triangles, and is useful for applications in a wide variety of fields

In the Class 10 CBSE Maths exam, terms for trigonometry, specifically, the two, each typically contributes around twelve to fourteen marks, including both direct questions and applications of trigonometry. The exact weightage may vary every year.

The hardest questions in Class 10 Trigonometry are, usually, complex word problems, proofs of trigonometric identities, and questions that require multiple steps with more than one trigonometric ratio. Example: A ladder 10 meters long is placed against a wall. If the foot of the ladder is 6 meters away from the wall, find the height at which the ladder touches the wall. Use trigonometric ratios to solve the problem.
