How do you identify a part 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...

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.
Names of the parts of a circle. A circle can have different parts based on position and shape. The most fundamental parts are the following: Center; Radius; Diameter; Circumference; Tangent; Secant; Chord; Arc; Segment; Sector; These parts may be present depending on how the lines are drawn in the circles.

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: Centre; Radius; Diameter; Circumference; Tangent; Secant; Chord; Arc; Segment; Sector; As we have already discussed the centre and radius of a circle. And the diameter is equal to the twice the radius.
In the previous sections, you learned the names given to several different parts of a circle – like the center, radius, diameter and circumference. However, there are many geometric elements related to a circle, which we’ll need to solve more complex problems: chord is a line segment whose endpoints lie on the circumference of a circle.
