Elements of Geometry and Trigonometry, with notes is a classic translation of Legendre’s comprehensive study of geometry and trigonometry, revised for use at West Point.

This edition presents foundational ideas in a clear, structured way, helping readers build a solid grasp of shapes, spaces, and the relationships between angles and sides.

The work blends geometric principles with practical problem solving. It covers the circle, regular polygons, planes and solids, the sphere, and the essentials of trigonometry, including sine, cosine, and tangent, with methods for solving both planar and spherical triangles. The accompanying notes aim to clarify concepts and connect them to broader mathematical thinking.
What you’ll experience

Structured introductions to proportion, figures, and measurements
Step‑by‑step treatments of geometric figures, solids, and angles
Foundational trigonometric tools and methods for solving triangles
Notes that illuminate the ideas behind the formulas and proofs

Ideal for students seeking a rigorous, historical foundation in geometry and trigonometry, as well as readers who appreciate a classic reference that connects theory to practice.
