- A line that "just touches" the circle as it passes by is called a Tangent. A line that cuts the circle at two points is called a Secant. A line segment that goes from one point to another on the circle's circumference is called a Chord. If it passes through the center it is called a Diameter. And a part of the circumference is called an Arc.

- 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.
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). What are the parts of a circle? Common Core State Standards.
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.
Secant. Chord. Arc. Segment. Sector. These parts may be present depending on how the lines are drawn in the circles. Details of the parts of a circle. Let’s look at a brief definition of the parts of a circle: Center. The center is a fixed point on the circle, which is used to define the circle.

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.
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.
