""Elements of Plane Geometry, Part 1: With an Appendix on Mensuration"" is a book written by Thomas Hunter and originally published in 1878. The book is a comprehensive guide to the principles and concepts of plane geometry, which is the study of two-dimensional shapes and figures. The book is divided into several chapters, each of which covers a specific topic in plane geometry, including lines, angles, triangles, quadrilaterals, circles, and polygons. The book provides clear and concise explanations of each concept, along with numerous examples and exercises to help readers understand and apply the principles of plane geometry. In addition, the book includes an appendix on mensuration, which is the branch of geometry concerned with the measurement of geometric figures and their properties. The appendix covers topics such as area, volume, and surface area, and provides practical applications of these concepts in real-world situations. Overall, ""Elements of Plane Geometry, Part 1: With an Appendix on Mensuration"" is an essential resource for anyone studying or teaching geometry, and remains a valuable reference for students and professionals alike.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
