Chapter 10 of Class 10 Maths, Circles, explores the properties of tangents and chords in relation to a circle. It covers key concepts like the perpendicularity of a tangent to the radius and the number of tangents from a point. MCQs test understanding of these properties, theorems, and their applications. This chapter enhances geometric reasoning and visualization skills. Circles play a crucial role in fields like design, engineering, and astronomy, making this topic essential for building a strong foundation in geometry.
