# What is a circle in geometry?

**Geometry**|

**Circles**)

**circle**. Definition: A

**circle**is the locus of all points equidistant from a central point. Definitions Related to

**Circles**. arc: a curved line that is part of the circumference of a

**circle**. chord: a line segment within a

**circle**that touches 2 points on the

**circle**.

Also question is, what is a circle simple definition?

A **circle** is a round, two-dimensional shape. All points on the edge of the **circle** are at the same distance from the center. The diameter of a **circle** is equal to twice its radius (d equals 2 times r). The circumference (meaning "all the way around") of a **circle** is the line that goes around the centre of the **circle**.

**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**. The a line segment from the center of the

**circle**to any point on the

**circle**is a radius of the

**circle**.

Thereof, what is Circle in math with example?

A **circle** is a shape with all points the same distance from its center. A **circle** is named by its center. Thus, the **circle** to the right is called **circle** A since its center is at point A. Some real world **examples** of a **circle** are a wheel, a dinner plate and (the surface of) a coin.

**Circles**. A **circle** is named by the point in the center. A radius is a line segment from the center of the **circle** to the edge. A diameter is a line segment that passes through the center of a **circle**. It has two points on the outside edge of the **circle**.
