The topic for this talk comes from a paper by Ross Finney in Mathematics Magazine, volume 43 (1970), pp 177-185. I have not added anything original and am only demonstrating what is shown in the article. Another source for similiar material is the New Math Library book by I.M. Yaglom, Geometric Transformations, Volume 1. In this book, the material is presented very carefully from the beginning with justification.
