NCERT Solutions Class 10 Maths Chapter 10 Circles
NCERT Solutions for Class 10 Maths Chapter 10 Circles is majorly focused on giving students a deep-seated understanding of tangents and their properties. A circle can be defined as a closed plane geometric shape where the locus of a point moves around a fixed point at a fixed gap such that the outline is equidistant from the center point. The chapter starts by elaborating on the position of a line with respect to a circle and how they are related. This line can be non-intersecting, meet the circle at two points meaning that it lies within the circle (secant), and touch the circle at one point only (tangent). We can also say that the tangent to a circle is a special case of the secant when the two endpoints of its corresponding chord coincide. This lesson consists of a host of theorems that make solving questions easier. Additionally, kids have the opportunity to learn about various terminologies associated with a tangent. As circles form an integral part of geometry, therefore, kids must go through the NCERT solutions class 10 Maths Chapter 10 with care and laser concentration.
This lesson is of great importance as the underlying concepts are used in several sister topics such as areas related to circles, constructions, and coordinate geometry. The Class 10 Maths NCERT Solutions Chapter 10 provides a wide variety of problem sums that can challenge a kid’s understanding eventually instilling ironclad concepts within him. With the help of this article, we will do a detailed analysis of NCERT Solutions Chapter 10 Circles and also you can find some of these in the exercises given below.

These theorems and formulas can be seen as tools to simplify a complicated question. Let us do a quick overview of the formulas which are frequently used in NCERT Solutions Class 10 Maths Chapter 10:
- Area of circle = πr2
- Circumference of a circle= 2πr
- Arc length of the sector of angle A= (A/360) * 2πr
- There is only one tangent at a point of the circle.
- The common point of the tangent and the circle is called the point of contact.
- The line containing the radius through the point of contact is also sometimes called the ‘normal’ to the circle at the point
