In this video, we break down the key concepts of circles in an easy-to-understand manner, ensuring that you have a solid foundation in geometry, which is crucial for scoring high marks in your board exams. Here’s a quick overview of what you’ll learn:

*What You Will Learn:*

1. *Basic Definitions and Concepts:*
Understand what a circle is and the essential terminology associated with it, such as radius, diameter, chord, arc, and secant.
Grasp the idea of a tangent to a circle, and how it differs from secants and chords.

2. *Important Theorems:*
*Theorem 10.1:* The tangent at any point of a circle is perpendicular to the radius through the point of contact.
*Theorem 10.2:* The lengths of tangents drawn from an external point to a circle are equal.

These theorems are crucial not only for your exams but also for understanding more advanced geometric problems. We’ll explain each theorem in detail, followed by examples that demonstrate how to apply them in different questions.

3. *NCERT Exercise 10.1 Solutions:*
Exercise 10.1 focuses on understanding the properties of tangents and circles. We walk through each question, explaining the step-by-step solutions. You’ll learn how to solve different types of problems, making sure you are well-prepared for both objective and descriptive questions in the exam.

4. *NCERT Exercise 10.2 Solutions:*
In this section, we deal with questions related to the equal lengths of tangents drawn from an external point. Each solution is carefully explained, ensuring you grasp the underlying concepts.
