Master plane and solid geometry with a practical, classroom-focused approach. This edition presents a complete course intended for high school and preparatory school use, balancing clear explanations with structured practice. It emphasizes reasoning by guiding students through demonstrations while building confidence with organized exercises.
The book is organized into plane and solid geometry, with a sequence of propositions, exercises, and modern geometry ideas. Distinctive features include gradually omitting steps in proofs, providing full demonstrations for beginners, and offering after‑proposition exercises and helpful hints. Constructions such as drawing parallels and erecting perpendiculars are presented before they are needed in proofs, helping students build essential skills.
- Teacher‑friendly structure that blends explanation with practice
- Stepwise proofs starting fully, then with selective omissions indicated by cues
- Exercises after each proposition to apply the principle right away
- Previews of key constructions and a broad range of problems for reinforcement
Ideal for readers who want a clear, guided path through foundational geometry with ample in‑text practice and review.
