## How do you introduce a circle?

A circle is the set of all points equidistant from a given point. The point from which all the points on a circle are equidistant is called the center of the circle, and the distance from that point to the circle is called the radius of the circle.

## What is the best definition of a 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. By definition of a circle, all radii have the same length. We also use the term radius to mean the length of a radius of the circle.

## What is the center of a circle?

The center of a circle is the point equidistant from the points on the edge. Similarly the center of a sphere is the point equidistant from the points on the surface, and the center of a line segment is the midpoint of the two ends.
