Geometric method for Möbius transformations: rules for calculation


Geometric method when pole is on the z-locus


Geometric method when z-locus is a line


What you must write to explain and justify the geometric method


Why the geometric method works: intersecting chords theorem


Why the geometric method works: intersecting secants theorem


Why the geometric method works: circle inversion theorem needed when z-locus is a line


When you want to find the locus of z given |z-a| = c|z-b|. Alternative methods. Circle of Apollonius.
