This book provides a geometrical experience that unifies Euclidean conceptsgenerally discussed in traditional high school geometry courses with variousNon-Euclidean views of the world. The book offers the readera "map" for a voyage through plane geometry and its various branches. It takesan informal tone while presenting the material in a reasonably rigorous manneras well as organizing it into a logical progression. Chapters are separatedinto independent units so readers can learn information in bites. Contains asummary at the conclusion of each chapter that includes a list of newdefinitions and theorems to aid in the organization of the material. PresentsEuclidean and non-Euclidean geometrics with a significant amount of backgroundinformation, that places much of the development of geometry in an historicalcontext. A valuable reference book on basic geometry for almostany reader seeking additional information on the subject.
