There are two main "slices" of a circle: The "pizza" slice is called a Sector . And the Segment , which is cut from the circle by a "chord" (a line between two points on the circle).
In the case of semi-circles, the circle is divided into two equal-sized sectors. The 2 radii meet at the part of the circumference of a circle known as an arc, formed a sector of a circle. Look at the following figure to distinguish between the minor sector and major sector.
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.
A segment of a circle is the region that is bounded by an arc and a chord of the circle. Learn the process of finding the area of a segment of a circle along with a few solved examples and practice questions.
- 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 is a path traced by a point that is equidistant from a unique point on the plane, this point is called the centre of the circle and the constant distance is called the radius of the circle. A segment is an interior region of a circle. The area enclosed by a segment and the angle subtended by a segment is called a sector.

In geometry it is the shape made when a solid is cut through by a plane. Example: The cross section of this circular cylinder is a circle. We don't draw the rest of the object, just the shape made when you cut through. Example: The cross section of a rectangular pyramid is a rectangle.
