Definition: A

**circle**is the set of all**points**in a plane that are equidistant from a given**point**called the center of the**circle**. For example, we can say**circle**O with radius r. O. r. The circumference of a**circle**is the length around the**circle**.

Similarly, it is asked, what is a point on a circle called?

The distance from a **circle's** center to a **point** on the **circle** is **called** the radius of the **circle**. A radius is a line segment with one endpoint at the center of the **circle** and the other endpoint on the **circle**.

**point**in geometry is a location. It has no size i.e. no width, no length and no depth. A

**point**is shown by a dot. A line is defined as a line of

**points**that extends infinitely in two directions. It has one dimension, length.

In this way, what are the parts of a circle?

**Important Circle Parts**

- Radius: The distance from the center of the circle to its outer rim.
- Chord: A line segment whose endpoints are on a circle.
- Diameter: A chord that passes through the center of the circle.
- Secant: A line that intersects a circle in two points.

**Polygons**. A **polygon** is a closed plane figure with three or more sides that are all straight. The following figure is not a **polygon** as it is not a closed figure. A **circle** is not a **polygon** as it does not have straight sides.
