Trigonometric ratios of an acute angle in a right-angled triangle
In this Class 10 Mathematics topic from the chapter “Introduction to Trigonometry,” students learn how the sides of a right-angled triangle define the trigonometric ratios of an acute angle. They identify the opposite side, adjacent side, and hypotenuse, then form sine, cosine, and tangent ratios using these sides. The topic builds the foundation for finding unknown sides or angles and for applying trigonometry to basic geometric problems.
