This document provides information about circles and various circle concepts. It defines a circle and discusses key terms like radius, diameter, chord, tangent, secant, and segment. It also provides formulas for calculating the circumference, area, sectors, and arcs of a circle based on the radius. The document serves as an educational reference on topics related to circles.

9. SECANT OF A CIRCLE2CIRCLEA circle is a simple shape consisting of those points in a plane which are at the same distance from a given point called the centre.

10. 3RADIUSThe common distance of the points of a circle from its center is called radius.

11. 4DIAMETERThe diameter is a line segment that connects two points on the circle and goes through the center of the circle. It is always twice as long as the radius.

12. 5CHORDA chord is any line segment whose endpoints are at any two points on the circle and it doesn’t pass through the centre.

13. 6TANGENTThe Tangent is a line which touches the circumference at only one point. A tangent is always perpendicular to the radius.

14. 7SECANTA secant is an extended chord: a straight line cutting the circle at two points.
