Here we are going to share that Names of parts of a circle. A circle can have different parts and based on the position and shape, these can be named as follows:
1. Centre
2. Radius
3. Diameter
4. Chord
5. Circumference
6. Sector
7. Arc
8. Segment

#Circle
A circle is a simple closed curve and it is not a polygon. Below is the image of a circle.


#Partsofacircle

#Centre
The center point of the entire circle. Point C is the centre of the circle.

#Radius
The line segment that connects the centre of circle to any point on the circle. OC is the radius of the circle.

#Diameter
The line segment that connects two points on the circle and passes through the centre of the circle. It is double the value of the radius. AB is the diameter of the circle.

#Chord
The line segment that connects two points on the circle but do not pass through the centre of the circle. DE is the chord of the circle.

#Circumference
It is the distance around the circle.

#Arc
An arc is the part of circumference. DFE is the arc of the circle.

#Sector
Sector is an interior region bounded by pair of radii and arc on one side. OBC is a sector of the circle where OB and OC are radius and BC is an arc.

#Segment
Segment is an interior region bounded by a chord and an arc.
