To invert a number in arithmetic usually means to take its reciprocal. A closely related idea in geometry is that of inverting a point. In the plane, the inverse of a point P with respect to a reference circle (Ã¸) with center O and radius r is a point P', lying on the ray from O through P such that. This is called circle inversion or plane inversion.
