Barron's E-Z Geometry (Barron's E-Z)

Known for many years as Barron's Easy Way Series, the new editions of these popular self-teaching titles are now Barron's E-Z Series. Brand-new cover designs reflect all new page layouts, which feature extensive two-color treatment, a fresh, modern typeface, and more graphic material than ever-- charts, graphs, diagrams, instructive line illustrations, and where appropriate, amusing cartoons. Meanwhile, the quality of the books' contents remains at least as high as ever. Barron's E-Z books are self-help manuals focused to improve students' grades in a wide variety of academic and practical subjects. For most subjects, the level of difficulty ranges between high school and college-101 standards. Although primarily designed as self-teaching manuals, these books are also preferred by many teachers as classroom supplements--and for some courses, as main textbooks. E-Z books review their subjects in detail, and feature both short quizzes and longer tests with answers to help students gauge their learning progress. Subject heads and key phrases are set in a second color as an easy reference aid. Barron's E-Z Geometry covers the "how" and "why" of geometry, with examples, exercises, and solutions throughout, plus hundreds of drawings, graphs, and tables.

And discover that learning geometry can be E-Z!

Author Larry Leff bypasses those dreary lists of geometric formulas for students to memorize. Instead, he makes the subject interesting and easy to learn by placing emphasis on the clear logic that underlies geometric principles, and then showing how to apply those principles in problem situations. He introduces students to angles and perpendicular lines, parallel lines, polygons, triangles, geometric inequalities, special quadrilaterals, ratios and proportions, the right triangle, circles, chords, tangents, secant segments, calculating areas and volumes, coordinate geometry, and locus and basic geometric constructions. New in this edition is fascinating chapter on Transformation Geometry and Symmetry. Review exercises follow every chapter with answers given at the back of the book. A quick-reference glossary defines geometric terms. Here is an ideal geometry text equally valuable for self-instruction or for classroom use.

Lawrence Leff is former Assistant Principal and Chairman of the Mathematics Department, Franklin D. Roosevelt High School, New York City.
