Synopsis
"Practical Geometry For The Use Of The Royal Military Academy At Woolwich" by Isaac Landmann is a comprehensive treatise that serves as a structured guide to practical geometry for military engineers. Originally published in 1805, this work presents definitions and elementary constructions, progressing through divisions, transformations, and mensuration of plane figures, and culminating in the mensuration of solids. It covers the description and construction of circles, ellipses, parabolas, polygons, and the five regular solids, featuring extensive problems and worked solutions that illustrate the application of geometry in fortification, surveying, artillery, and map-making. The text includes sections on the addition, subtraction, multiplication, and division of plane figures, mensuration of surfaces and solids, and practical plane trigonometry. It also provides methods for constructing and transforming figures using geometric rules and physical models, along with instructions for calculating heights, distances, and fortification coordinates. An appended discussion on the New French Weights and Measures completes the volume.
