Let’s break this down step by step so you fully understand why this is always true. 📌 What Is a Right Triangle? A right triangle is a triangle with one 90-degree angle. The side opposite this right angle is called the hypotenuse. The other two sides are called the perpendicular and the base — they are always shorter than the…

If sin A = 1/2 , find all the Trigonometric Ratios – Class 10
In this blog, let’s understand how to find all six trigonometric ratios when sin A = 1/2 using Triangle and Identity method 1st Method : Triangle Method We are given: sin A = 1/2 By definition, sin A = Perpendicular / Hypotenuse So, we can assume: Perpendicular (P) = 1 Hypotenuse (H) = 2 We assume the simplest…
Trigonometric Ratios Are Not Products — And They Belong to Acute Angles : Class 10
Many students think expressions like sin A, cos A, etc., mean “sin × A” or “cos × A”. But this is completely incorrect. These are functions, not multiplications. ✅ These Ratios Do NOT Mean Multiplication Expression Wrong Assumption Correct Meaning sin A sin × A (incorrect) sine of angle A = Perpendicular / Hypotenuse cos A cos…
How to Identify Hypotenuse, Base, and Perpendicular in a Right Triangle – Class 10 Trigonometry
Understanding the parts of a right-angled triangle—hypotenuse, base, and perpendicular—is key to mastering Class 10 Trigonometry. These three sides form the foundation for calculating ratios like sine, cosine, and tangent, and are critical in real-life applications such as construction, architecture, and physics. What is a Right-Angled Triangle? A right-angled triangle is a triangle where one angle is exactly 90°. The…
