Circle - a geometric figure bounded by a circle. In other words, the circle - this is the set of all points in the plane whose distance to a given point (the center circle) does not exceed a predetermined distance (radius). The circumference of a circle is the limit.
Circle - a centrally symmetric figure.
When you rotate the plane of the center of the circle moves in on itself.
