In geometry, a point that is well-distant from the boundaries[?] of a figure. For instance, for a circle, the center is defined as the point equidistant from all points on the circle's boundary. Similar definitions can be made for other shapes in various geometries, though for arbitrary complex shapes there may be several definitions considered appropriate in some circumstances.
