For example: A circle drawn with the help of a coin. A circle is a closed curve in a plane. BACKSlide7: This fixed point (equidistant) inside a circle is called centre. A circle is a closed curve consisting of all points in a plane which are at the same distance (equidistant) from a fixed point inside it. O Centre A circle A circle has one and only one centre. BACKSlide8: The distance around a circle is called its circumference. O Centre A circle A BACKSlide9: A circle divides a plane into three parts. 2. Interior of a circle 3. Exterior of a circle A plane The interior of a circle together with its circumference is called the circular region. BACKSlide10: Radius A line segment that joins any point on the circle to its centre is called a radius.

Minor segment does not contain the centre of the circle. The part of the circular region enclosed by a major arc and the chord is called a major segment. Major segment contains the centre of the circle.
