Chapter 10 - Circles

Course for understanding the chapter like never before!

The circle is a set of points in a plane in which the distance of a point from the centre is same as the distance of the other points from the centre. The distance between any of the points and the centre is called the radius. The diameter is double of a radius. A circle is a simple closed figure.

We, at ScoreX™, have designed a well-planned course for your Class 9 Maths Ch-10 Circles. We have created all the courses in such an interesting manner which enables you to score more.

What is the format of the course?

In the course of CBSE class 9 Maths chapter 10, we are covering all the essential points. Some of the components of this course are: -

1.     Basic definitions of circle based terms

Major definitions related to the concept of the circle are the definition of chord, arc, and sector like a piece of a circle between two points is called an arc and other definitions.

2.     Tangent to a circle

A tangent to a circle is a line that meets the circle at only one point, and there is only one tangent at a point of the circle. It is a special case of secant when the two end points of its corresponding chord coincide.

3.     Theorems of the circles

There are a number of theorems related to the circles and some important one state that the perpendicular from the centre of a circle to a chord bisects the chord and also equal chords always subtends equals angles.
