The points are all the same distance from the center of the circle. The distance between the center and any point is the radius of the circle.
A collection of points in a plane that are the same distance from a center point forms a circle. The center point is known as the center of the circle, and the constant distance from this center to any point on the circle is called the radius. All points on the circle maintain this uniform distance from the center, creating a perfectly round shape.
