An Elementary Treatise On Plane And Solid Geometry is a mathematical textbook written by Benjamin Peirce and first published in 1869. The book is designed to provide a comprehensive and accessible introduction to the principles of plane and solid geometry, covering a range of topics from basic concepts such as points, lines, and angles, to more advanced topics such as conic sections, spherical geometry, and the geometry of space. Peirce's approach is highly systematic and logical, with clear explanations of key concepts and theorems, and numerous examples and exercises to reinforce understanding. The book is divided into two main sections, with the first section focusing on plane geometry and the second section covering solid geometry. Throughout the book, Peirce emphasizes the importance of visualization and intuition in understanding geometric concepts, and provides numerous diagrams and illustrations to aid in this process.Overall, An Elementary Treatise On Plane And Solid Geometry is an essential resource for anyone studying mathematics, physics, or engineering, and remains a classic text in the field of geometry.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
