Circles | Exercise 10.2 | Chapter 10 | Class 10 Maths | NCERT | CBSE | SR Academy

Welcome to SR Academy, your complete learning destination for Class 10 Maths NCERT Solutions and Concept-based Explanations! In this video, we will cover Chapter 10 – Circles (Exercise 10.2) from the NCERT Class 10 Mathematics textbook, strictly as per the latest CBSE 2024–25 syllabus. This session provides a step-by-step explanation of each question from Exercise 10.2, focusing on theorems related to tangents drawn from an external point to a circle. These concepts are highly important for CBSE Board Exams, as they are frequently asked in both objective and long-answer formats. 📖 Chapter Overview: In the previous exercise (10.1), we learned the basic properties of tangents and how a tangent touches the circle at exactly one point. Now, in Exercise 10.2, we move deeper into understanding theorems and properties related to tangents drawn from a single external point to a circle. You’ll explore the following key theorems: 1️⃣ The tangent at any point of a circle is perpendicular to the radius through the point of contact. 2️⃣ The lengths of tangents drawn from an external point to a circle are equal. These two theorems are the foundation for many geometry and reasoning questions that appear in exams. This video will make these theorems easy to understand through diagrams, proofs, and examples. 🧮 Topics Covered in This Video: ✅ Theorem 10.1 – Tangent ⟂ Radius at the Point of Contact ✅ Theorem 10.2 – Lengths of Tangents from an External Point are Equal ✅ Step-by-step proofs and reasoning ✅ NCERT Exercise 10.2 full solution ✅ Conceptual understanding with diagrams ✅ Important examples and board-oriented questions ✅ Relation between tangents, radii, and chords 💡 Key Learning Outcomes: 🔹 Understand and prove tangent-related theorems 🔹 Learn how to apply theorems in solving geometry problems 🔹 Strengthen understanding of circle geometry and tangency 🔹 Prepare effectively for CBSE board exam geometry questions 🔹 Build the foundation for higher-level geometry concepts 🎯 Why Watch This Video: ✔️ 100% NCERT-based Exercise 10.2 Solutions ✔️ Based on the latest CBSE 2024–25 syllabus ✔️ Easy, step-by-step conceptual explanations ✔️ Visual understanding using clear diagrams ✔️ Perfect for CBSE Class 10 Board Exam Preparation ✔️ Helpful for both English and Hindi medium students 📚 By the End of This Video, You Will Be Able To: ⭐ State and prove both tangent theorems correctly ⭐ Understand the geometry of tangents drawn from a point ⭐ Solve all Exercise 10.2 questions confidently ⭐ Apply tangent theorems in real-life and exam problems ⭐ Build strong preparation for geometry-based board exam questions At SR Academy, we make Maths learning simple, visual, and exam-oriented, helping students understand each concept thoroughly.
