A circle is a plane figure consisting of a curve in which every point is equidistant from a fixed point called the center.
That point which is equidistant from every point on the circumference. It's just called the center.
The center of the circle.
All points on the circumference of a circle drawn on a plane are equidistant from the single point on the plane which is the center of the circle.
The center of a circle is the point from which all points on the circle are equidistant.

It is the centre of the circle
The center of the circle.
circle
The center of the circle. That's how the circle is defined. (The collection of all points on a plane equidistant from a fixed point. The fixed point is the center and the fixed distance is the radius.)
All points on the circumference of a circle drawn on a plane are equidistant from the single point on the plane which is the center of the circle.
The center of a circle is the point from which all points on the circle are equidistant.
Perhaps the answer to the question is "equidistant".
A circle
THE center
The locus of a moving point so that it is equidistant from another fixed point (i.e. the distance between them is always constant) is a circle.
