Inversive geometry is a branch of geometry that focuses on properties and relations of figures that are invariant under the process of inversion in a circle (or sphere in higher dimensions). This type of transformation maps points outside a given circle to points inside the circle and vice versa, while points on the circle itself remain unchanged. Key concepts and characteristics of inversive geometry include: 1. **Inversion**: The basic operation in inversive geometry is the inversion with respect to a circle.
