Class 10 Maths Chapter 6 Triangles One Shot | Similarity, BPT Proof & PYQs | Board Exam 2026

In this video, Sachin Bhaiya provides a complete Rapid Revision of Chapter 6: Triangles for Class 10 Maths. This one-shot covers all concepts, formulas, theorem proofs (BPT), and the most important questions asked in CBSE Board Exams, including PYQs (Previous Year Questions).

🔥 Topics Covered:
- Basic Proportionality Theorem (BPT/Thales Theorem): Complete proof and explanation.
- Converse of BPT: Understanding the concept and application.
- Similarity of Triangles: Rules and criteria (AAA, SAS, SSS).
- Important Question Types:
- Finding missing side using BPT.
- Questions involving Trapezium and Diagonals.
- Proving lines are parallel using Converse of BPT.
- Similarity based numericals (finding angles and sides).
- Advanced Proof Questions (Perpendiculars on AC, 1/x + 1/y = 1/z type).
- Previous Year Questions (PYQs): 2025 and older board questions solved.
