Master geometry and trigonometry with a trusted classic, revised for today’s students.
This edition presents A. M. Legendre’s Elements of Geometry and Trigonometry in a form suited to modern instruction. It surveys the foundations of geometry, then builds toward practical tools in plane and spherical trigonometry, with an emphasis on general, abstract reasoning. The book shows how geometric ideas connect to measurements, shapes, and real-world problems.
- Clear definitions, propositions, and worked problems that illustrate key concepts
- Coverage of plane and spherical trigonometry, including applications to heights, distances, and areas
- Methods for constructing figures, using instruments, and applying logarithms and related techniques
- Structured content that moves from basics to more advanced topics like polyhedrons and solid geometry
Ideal for students beginning a study of geometry and trigonometry or readers looking for a solid, traditional reference on the subject.
