Mr. Matt Hughes will give the talk on Friday, April 2 at noon in Math 417. This lecture will be open to all.
Abstract: A brief discussion of geometric inversion and its various useful properties. We will first prove some elementary properties such as angle preservation, and the correspondence between lines and circles. We will go on to use these to elegantly prove Ptolemy's inequality and other seemingly difficult problems.
