NCERT Class 10 Mathematics Chapter 10 Circles PDF Download
Chapter Overview
Circles is Chapter 10 of NCERT Class 10 Mathematics and focuses on the geometric properties of circles, tangents, and their relationship with the radius. The chapter explains the concept of a tangent to a circle and establishes important theorems related to tangents drawn from a point outside a circle. Students learn that the tangent at any point of a circle is perpendicular to the radius through the point of contact and that the lengths of tangents drawn from an external point to a circle are equal. These results are applied to solve various problems involving circles and tangents.
