Class 9 Maths | Chapter 7 – Triangles | Exercise 7.3 Question 4

In this video, JP Sir explains Exercise 7.3 Question 4 from Chapter 7 – Triangles (Class 9 NCERT Maths) with a neat diagram and step-by-step proof. You’ll learn how equal altitudes in a triangle can be used with the RHS congruence rule to prove that the triangle is isosceles. 📘 What you will learn in this video: 🔹 Understanding altitudes BE and CF in triangle ABC 🔹 Identifying the right-angled triangles formed by altitudes 🔹 Applying the RHS (Right angle–Hypotenuse–Side) congruence rule 🔹 Proving the congruence of two right triangles 🔹 Concluding that AB = AC, so ∆ABC is isosceles 🔹 Writing clean, logical proof-based answers 🎯 Why this question is important: 🔹 Shows a smart use of altitudes in congruence proofs 🔹 Strengthens understanding of the RHS congruence criterion 🔹 Important for exam-oriented geometry questions 🔹 Improves confidence in linking constructions to results 👉 Watch the full explanation to see how equal altitudes lead to an isosceles triangle. 👍 Like, Share & Subscribe to Math Station for more Class 9 Maths videos by JP Sir. 🔖 Hashtags #Class9Maths #Chapter7Maths #Triangles #Exercise7_3 #NCERTClass9Maths #CBSEClass9 #TriangleCongruence #RHS #Altitudes #JPSir
