HYPERBOLIC PLANE-GEOMETRY REVISITED
... Construct a circle touching three given circles of the Euclidean plane.
A nice construction is the following:
• Draw the point P of power of the given circles c1 , c2 , c3 and an axis of similitude of certain three
centres of similitude.
• Join the poles P1 , P2 , P3 of this axis of similitude with ...
