1. its centre
2.a radius
3.a segment
4. a sector
5.a point in its exterior
6.a point
7. a point in its interior other than centre
8. diametre
9. an arc​

Answer 1

Parts of a Circle : -

1. Centre : C is the centre of the circle.

2. A Radius : The line segment joining the centre and any point on the circle is called its Radius.

• Here , CA = CB = CR are the radius of the circle .

3. A Segment : A region in the interior of the circle enclosed by a chord and an arc is called the Segment.

• Here , PBS is the segment of the circle(y) .

4. A Sector : A region in the interior of the circle enclosed by an arc on one side and a pair of radii on the other two sides is called a Sector.

• Here , ACR is the sector of the circle(x).

5. A point in its exterior : Q is the exterior point of the circle.

7. A point in its exterior other than Centre : Z is the interior point of the circle other than the centre.

8. Diametre : The line segment joining any two points on the circle ads passing through the centre is called Diametre .

• Here , AB is the Diametre of the circle.

9. An Arc : A portion of the circle is known as Arc.

• Here , MN is the arc of the circle.
