Excerpt from Notes on Elements of (Analytical) Solid Geometry
The projection of a line on a plane is the line containing the projections of its points on the plane.
When one line or several lines connected together enclose a plane area, the area enclosed by the projection of the lines is called the projection of the first area.
The idea of projection may be in the case of the straight line thus extended: if from the extremities of any limited straight line we draw perpendiculars to a second line, the portion of the latter intercepted between the feet of the perpendiculars is called the projection of the limited line on the second line.

Paperback. Condition: New. Print on Demand. This book explores the theoretical foundations of solid geometry, a branch of Euclidean geometry which addresses the unique geometric properties of solid figures in three-dimensional space. The author begins with an introduction to the fundamental concepts used in solid geometry, such as the coordinate system, the equation of a plane, and the direction cosines of a line. The book then explores more advanced topics including the equation of a sphere, the intersection of planes, and the conditions for perpendicularity and parallelism. The author provides numerous examples and exercises throughout the book to aid comprehension and mastery of the material. This book is written in a clear and concise manner, making it a valuable resource for students of mathematics, engineering, architecture, and anyone else interested in developing a solid understanding of three-dimensional geometry. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
