major objective of this lecture is to present on The Circle. In a plane,each point of the circle is at equal distance from a fixed point.The fixed point is called the centre of the circle. The distance from centre to any point on the circle is called radius of the circle. A Line segment passing through the centre of the circle and whose end points lie on the circle is called the diameter of the circle. The length of the circle or the distance around it is called circumference of the circle. The distance from centre to any point on the circle is called radius of the circle.
