- 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.

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...

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.
Activity. Watch: Parts 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...
Jul 19, 2023 · The circle consists of several key parts, including the radius, diameter, circumference, sector, arc, and chord. Step-By-Step Guide to Identifying Parts of a Circle. Let’s take a closer look at each part: Step 1: Spot the Radius. The radius of a circle is a line segment from the center of the circle to any point on the circle.
The parts of a circle can be identified by looking at the shape of the circle and measuring different points, such as the radius, diameter, and circumference. Other parts, such as the chord, arc, and sector, can be identified by drawing lines and angles within the circle.
Jul 18, 2012 · Tangent Circles: Two or more circles that intersect at one point. Two circles can be tangent to each other in two different ways, either internally tangent or externally tangent. If the circles are not tangent, they can share a tangent line, called a common tangent. Common tangents can be internally tangent and externally tangent too.
