Circle
A circle is a closed curve consisting of all the parts in aplane which are at the same distance from a fixed pointsinside it. This fixed point inside a circle is called centre. Acircle has one and only one center. Example of circleBangle, CDS, cycle, and Round Table. Circle in which aline segment that joins any points on the circle to itscentre is called a radius. A line segment that join any twopoints on the circle are passes through its centre is calleddiameter. A line segment that joins any two points on thecircle is called a chord and a line that intersects the circleat any two points on the circle is called secant. And it is aline that cross the circle at exactly one points on the circle.This point is called of tangency.
