A clear, classroom-friendly start to geometry that invites discovery

This edition presents plane geometry in a simple, step-by-step form designed for common schools. It follows the model of Colburn’s arithmetic, aiming to make geometric ideas accessible without sacrificing rigor.

The book emphasizes a hands-on method: learners discover truths through guided questions, concrete shapes, and carefully explained theorems. It also provides plentiful definitions, corollaries, and practical exercises to build understanding and confidence.

Plain, novice-friendly definitions that align with students’ natural ways of thinking about form and space
Systematic demonstrations that show how geometric ideas are proved, not just stated
Illustrative questions and exercises that connect theory to measurements and everyday objects
Structured progression from basic concepts to more advanced topics in plane geometry

Ideal for readers beginning geometry in a school setting or at home, this edition helps learners build a solid foundation in reasoning, measurement, and mathematical form.
