  3. 3. Circle A circle is a closed curve consisting of all the parts in a plane which are at the same distance from a fixed points inside it. This fixed point inside a circle is called centre. A circle has one and only one center. Example of circle Bangle, CDS, cycle, and Round Table. Circle in which a line segment that joins any points on the circle to its centre is called a radius. A line segment that join any two points on the circle are passes through its centre is called diameter. A line segment that joins any two points on the circle is called a chord and a line that intersects the circle at any two points on the circle is called secant. And it is a line that cross the circle at exactly one points on the circle. This point is called of tangency. 3
