New Plane and Solid Geometry

*New Plane and Solid Geometry* by Webster Wells is a classic textbook that systematically introduces the principles of Euclidean geometry. It begins with foundational plane geometry—covering points, lines, angles, triangles, and circles—then progresses to solid geometry, including prisms, pyramids, cylinders, cones, and spheres. Each topic is explained with precision, supported by diagrams, theorems, and proofs. The book emphasizes logical reasoning, problem-solving, and visual understanding through structured exercises. Designed for secondary or early college students, it remains a timeless resource for learning spatial relationships and geometric logic, making complex concepts accessible through step-by-step progression and clear illustrations.
