A new solution of Apollonius’ problem based on stereographic projections of Möbius and Laguerre planes
In this paper we give a new proof of Apollonius’ problem based on the stereographic projection in spherical model of Möbius geometry and cylinder model of Laguerre geometry.
A note on a problem of Apollonius
Degenerate cases of the problem of Apollonius, to construct a circle tangent to each of three given circles, are discussed and exhaustively classified for proper circles (finite and non-zero radius).Expand
