Class 9 Maths | Chapter 7 – Triangles | Exercise 7.3 Question 1

In this video, JP Sir solves Exercise 7.3 Question 1 from Chapter 7 – Triangles (Class 9 NCERT Maths) with a clear figure and step-by-step proof. This question beautifully uses isosceles triangle properties along with triangle congruence (SSS/RHS) to prove multiple results from a single construction. 📘 What you will learn in this video: 🔹 Understanding two isosceles triangles ABC and DBC on the same base BC 🔹 Drawing and using the construction of AD intersecting BC at point P 🔹 Proving ∆ABD ≅ ∆ACD using congruence criteria 🔹 Proving ∆ABP ≅ ∆ACP with proper reasoning 🔹 Showing that AP bisects ∠A and ∠D 🔹 Proving that AP is the perpendicular bisector of BC 🔹 Writing neat, step-by-step exam-oriented geometry proofs 🎯 Why this question is important: 🔹 Combines isosceles triangle properties + congruence rules 🔹 One question, multiple results – very exam-relevant 🔹 Builds strong understanding of perpendicular bisector and angle bisector 🔹 Improves diagram interpretation and logical flow in proofs 👉 Watch till the end to see how one construction leads to four powerful conclusions. 👍 Like, Share & Subscribe to Math Station for more Class 9 Maths videos by JP Sir. 🔖 Hashtags #Class9Maths #Chapter7Maths #Triangles #Exercise7_3 #NCERTClass9Maths #CBSEClass9 #TriangleCongruence #IsoscelesTriangle #GeometryProof #JPSir
