- Circle and its Parts. The different parts of a circle are listed below: Circumference. Radius. Diameter. Chord. Tangent. Secant. Arc. Segment. Sector. Let us discuss each of the parts in detail.
- Circumference of a Circle. The circumference of a circle is its boundary. In other words, when we measure the boundary or the distance around the circle, that measure is called the circumference and it is expressed in units of length like centimeters, meters, or kilometers.
- Radius of a Circle. The radius of a circle is the length of the line segment joining the center of the circle to any point on the circumference of the circle.
- Diameter of a Circle. The diameter of a circle is a line segment that passes through the center of the circle and with endpoints that lie on the circumference of a circle.
Based on the shape and position, there are different parts of a circle in geometry that can be listed as center, radius, circumference, diameter, chord, arc, segment, tangent, secant, and sector. It will be easy to identify and label parts of a circle using the diagram shown below.

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. Circumference 5. Tangent 6. Secant 7. Chord 8. Arc 9. Segment 10. Sector As we have already discussed the centre and radius of a circle. And the diameter is equal to the twice the radius. Let us see the other part...
The circumference of a circle can be defined as the distance around it. This can be understood with the help of an example. Suppose a wire of length 10 cm is bent so that it forms a circle. Here, the circumference is equal to the length of the wire, i.e. 10 cm. How to draw a circle? Figure 1 given above, represents a circle with radius ‘r’ and cent...
A part of a circumference of the circle is known as an arc. An arc is a continuous piece of the circle. The arc PAQ is known as the minor arc and arc PBQ is the major arc. Now go through the circular region which is cut off from the rest of the circle by a secant or a chord. Segment Part of a circle bounded by a chord and an arc is known as a segme...

The parts of a circle are the circle, center, radius, diameter, circumference, arc, area, chord, secant, tangent, sector and segment. The definition of a circle is a closed plane figure where all points in a plane are equidistant, (the radius), from a given point (the center).
Here we will learn about the different parts of a circle including how to identify the key parts of a circle from a diagram, how to identify the key parts of a circle from a definition and how to draw a circle with the different parts labelled e.g. the diameter of a circle.
All circles have a circumference, diameter and radius. They can be measured using a ruler or tape measure. The circumference is the distance all the way around a circle. The diameter is the...
The different parts of a circle are radius, diameter, chord, secant, tangent, minor arc, major arc, minor segment, major segment, minor sector, and major sector. What is the perimeter of a circle? c = 2$\pi$r, where c is the circumference and r is the radius.
