The Elements of Plane Geometry offers a clear, classroom‑friendly tour of core geometric ideas. This edition presents the circle, its properties, and fundamental constructions, along with ratio and proportion and the broader concept of geometric reasoning. It combines definitions, theorems, and practical problems to build both understanding and problem‑solving skill.

This book is structured to support guided study and independent practice. It shows how geometric ideas connect to measurement, shapes, and the logic of proof, while emphasizing methods you can apply with simple tools and clear reasoning. The material is framed for school use, with explanations that progress from elementary concepts to more advanced topics.

Foundational circle theory: center, radius, diameter, arcs, sectors, chords, tangents, and inscribed figures.
Properties of symmetry, congruence, and proportional reasoning central to geometry.
Worked demonstrations and a range of exercises to develop proof and construction skills.
Problem sets that develop this edition’s emphasis on method, sequence of propositions, and practical applications.

Ideal for readers pursuing a practical understanding of plane geometry, and for instructors selecting a structured, proven sequence of topics.

Store Description

We first started out as ?The Paperback Exchange,? a chain of physical bookstores where we would part exchange your beloved books for new stories to transport you to faraway places. However, as shopping started to evolve to online shops and marketplaces, we bid our stores goodbye to become ?PBShop.? This transition has only allowed us to blossom as we now ship thousands of titles to book lovers across the globe. We pride ourselves in being a community of local book lovers which allows our passion and devotion to shine in everything we do. In 2020 we not only celebrated our 20th birthday but our 1st birthday as being completely employee owned after becoming an E.O.T in September 2019. We are proud to be different and embrace standing apart on a book mountain by working from a virtual inventory which allows us to provide thousands of books that may be difficult to get for your bookshelf or your studies. Working with a number of different suppliers allows us to explore other avenues such as puzzles, sheet music and even stationery so we really do have something for everyone. Life is about being versatile in all realms of existence. If this is your first visit or you are a returning customer, we would like to welcome you to the PBShop family, for there is no friend as loyal as a book.
