📘 Detailed Solution of Exercise 15D | Application of Theorem 1 & Its Converse | Similarity | Class 10 ICSE 2026 | R.K. Bansal Selina

Welcome to Let’s Solve with Ranita!
In this video, I have explained the complete, step-by-step solutions of Exercise 15D from the latest edition of Concise Mathematics by R.K. Bansal (Selina) for Class 10 ICSE 2026.

This exercise focuses on Theorem 1 and its Converse in the chapter Similarity, making it a very important topic for your ICSE Board Exam preparation.

✨ What is Theorem 1?

A line drawn parallel to one side of a triangle divides the other two sides in equal proportion.
You will learn how to identify proportionality, apply the theorem correctly, and understand how the converse of the theorem helps in proving lines parallel.

📚 What You Will Learn in This Video:

✔ Application of Theorem 1 in different geometrical problems
✔ How to use the Converse of Theorem 1 to establish parallel lines
✔ Step-by-step solving of each question from Exercise 15D
✔ Concepts linked with Similarity of Triangles
✔ Fully explained solutions for better understanding and exam readiness

This video is perfect for ICSE Class 10 students who want clear, simple, and exam-oriented explanations.
