""An Elementary Course In Synthetic Projective Geometry"" by Derrick Norman Lehmer is a comprehensive textbook that provides a thorough introduction to the principles and concepts of synthetic projective geometry. The book is designed for students who have a basic understanding of Euclidean geometry and are interested in exploring more advanced topics.The book begins with an overview of the basic concepts of projective geometry, including points, lines, and planes. It then progresses to more advanced topics such as conics, quadrics, and the cross-ratio. The author also covers the principle of duality, which allows for the transformation of points into lines and vice versa.Throughout the book, the author provides numerous examples and exercises to help students develop their understanding of the material. The exercises range from simple problems to more complex ones, and many of them include detailed solutions.One of the unique features of the book is its use of historical examples to illustrate the concepts. The author includes biographical sketches of prominent mathematicians who made significant contributions to the development of projective geometry, such as Desargues and Pappus.Overall, ""An Elementary Course In Synthetic Projective Geometry"" is an excellent resource for students who are interested in exploring the fascinating world of projective geometry. The book is well-written, easy to follow, and provides a solid foundation for further study in the field.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
