Plane and Solid Geometry

*Plane and Solid Geometry* by Webster Wells is a classic geometry textbook that offers a clear, logical progression through Euclidean geometry. It begins with the basics of plane geometry—points, lines, angles, triangles, polygons, and circles—before advancing to solid geometry, including prisms, pyramids, cylinders, cones, and spheres. Each concept is carefully explained with diagrams, theorems, and proofs, supported by structured exercises that build reasoning and spatial understanding. Designed for high school and early college students, the book blends rigorous logic with visual learning. Its timeless approach makes it a strong foundation for anyone seeking mastery in classical geometric principles.
