Offers an introduction to the principles of geometry, from lines and angles to polygons, proofs, and coordinates.

Sir Cumference, Radius, and Sir Vertex search for Edgecalibur, the sword that King Arthur has hidden in a geometric solid.

"This new edition in Barron's Easy Way Series contains everything students need to prepare for a geometry class. [The book] provides key content review and practice exercises to help students learn geometry the easy way. Topics covered in this detailed review of algebra include the 'how' and 'why' of geometry, with examples, exercises, and solutions throughout, plus hundreds of drawings, graphs, and tables. Practice questions in each chapter help...

"Shape reveals the geometry underneath some of the most important scientific, political, and philosophical problems we face. Geometry asks: Where are things? Which things are near each other? How can you get from one thing to another thing? Those are important questions. Geometry doesn't just measure the world-it explains it. Shape shows us how"-- Provided by publisher.

"In this . . . book, readers will learn that spheres--3-D geometric figures--are familiar objects. In fact, they may see or even play with spherical items every day"--Provided by publisher.

Explores cubes, focusing on their features with different examples.

"Friends identify the shapes of things in their neighborhood, create new shapes by joining and separating existing ones, and discover why certain shapes are useful for building structures"--Provided by publisher.
