Mental Geometry: Or Generalizations Of Geometrical Demonstrations In Planes, Solids, And Spherics is a book written by Henry H. Holloway in 1864. The book provides a comprehensive study of geometry, covering various topics related to planes, solids, and spherics. It is a valuable resource for students, teachers, and anyone interested in the field of mathematics.The book is divided into three parts, each focusing on a different area of geometry. The first part deals with plane geometry and covers topics such as angles, triangles, circles, and polygons. The second part covers solid geometry and discusses topics such as prisms, pyramids, cylinders, and cones. The third part deals with spheric geometry and covers topics such as spherical triangles, spherical polygons, and the geometry of the celestial sphere.The book is written in a clear and concise manner, making it easy to understand even for those new to the subject. It includes numerous examples and diagrams to help illustrate the concepts discussed. The author also provides generalizations of various geometric demonstrations, which can help students develop a deeper understanding of the subject.Overall, Mental Geometry: Or Generalizations Of Geometrical Demonstrations In Planes, Solids, And Spherics is a valuable resource for anyone interested in the field of mathematics. It provides a comprehensive study of geometry and covers a wide range of topics related to planes, solids, and spherics. The book is well-written, easy to understand, and includes numerous examples and diagrams to help illustrate the concepts discussed.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations.
