Created by Megha Aggarwal, Last Updated 07-Aug-2019, Language:English
Description
A circle is a simple closed shape which divides the plane into two regions: an interior and an exterior. The distance between any points on the circle and center of the circle is called the radius. we will study about the various properties of circle and about its chord in this chapter.
Audience
These video lectures have been prepared exclusively for all English medium state board and central board class 9th students to have the understanding on basic properties of Circles.
