Exercise 8.1 introduces Trigonometric Ratios using a right-angled triangle.
Students learn how to relate the sides of a right triangle to its angles. The exercise explains the six main ratios:
Sine (sin)
Cosine (cos)
Tangent (tan)
Cosecant (cosec)
Secant (sec)
Cotangent (cot)
Using these, students solve questions based on:
✔ Identifying opposite, adjacent, and hypotenuse sides
✔ Finding the value of trigonometric ratios
✔ Using the given side lengths to calculate other ratios
✔ Understanding the ratios for acute angles
This exercise builds the foundation for all later trigonometry concepts in Class 10.#Class10Maths
