# RD Sharma Class 10 Chapter 10 (Circles) Solutions

Share**RD Sharma Class 10 Chapter-10 Circles** revolves around two theorems related to a tangent. The first theorem states that when you draw a tangent at any point of a circle, then it will become perpendicular to the radius at the common point. Develop an in-depth understanding of this theorem by practicing questions from the first exercise.

According to the second theorem, when we draw a couple of tangents from an external point to a circle, then they both are equal. To master this theorem, you will find a lot of questions to build your understanding level in the second exercise of Chapter-10 RD Sharma Class 10 textbook.
