The branch of mathematics in which the heights and angles of a right triangle can be correlated is trigonometry. The word 'trigonometry' is derived from the Greek words 'tri' meaning three , 'gon' meaning sides , and 'metron' meaning measure justifying its relationship with the three-sided polygon triangle.
Class 10th Maths Chapter 8 exercise 8. The angles discussed here are predominantly acute angles, for simplicity, though it can be extended to obtuse angles. Trigonometry has a lot of real-life applications- it is used in various industries, and even simple distance height problems can be solved with trigonometry. Those types of real-life problem-based questions will also be encountered by the student later in Maths Chapter 8 exercise 8.
There are six trigonometric ratios of angle, namely sin, cos, tan, cosec, sec, cot. Of which cosec, sec, and cot are the inverse of sin cos and tan about which you would learn more in detail in Class 10 Maths Chapter 8 exercise 8. In the right triangle, the side opposite to the right angle i. Let us consider a non-right acute angle of the triangle, say A, and the trigonometric ratios are defined based on the adjacent side of the angle and the opposite side of the angle.
The trigonometric ratios are represented as sin A meaning sin of angle A. Class 10 Maths ex 8. This is well addressed in the Exercise 8.
Referring to these notes for a better understanding of the relationship between the trigonometric ratios of the angle. State whether the following statements are true or false.
Justify your answer. Trigonometry is the study of relationships 10th Ncert Maths Chapters World University between the sides and angles of a right-angled triangle. Trigonometric ratios of an acute angle in a right triangle express the relationship between the angle and the length of its sides. Note: The values of the trigonometric ratios of an angle do not vary with the lengths of the sides of the triangle, if the angle remains same.
An equation involving trigonometric ratios of an angle is called a trigonometric identity, if it is true for all values of the angle s involved. Solution: Ex 8.
