Harold Jacobs's Geometry created a revolution in the approach to teaching this subject, one that gave rise to many ideas now seen in the NCTM Standards. Since its publication nearly one million students have used this legendary text. Suitable for either classroom use or self-paced study, it uses innovative discussions, cartoons, anecdotes, examples, and exercises that unfailingly capture and hold student interest.
This edition is the Jacobs for a new generation. It has all the features that have kept the text in class by itself for nearly 3 decades, all in a thoroughly revised, full-color presentation that shows today's students how fun geometry can be. The text remains proof-based although the presentation is in the less formal paragraph format. The approach focuses on guided discovery to help students develop geometric intuition.
Jacobs' text provides a clearly written, carefully developed course in high school geometry. The text covers lines and angles, congruence, inequalities, parallel lines, quadrilaterals, area, similarity, right triangles, circles, concurrence theorems, and regular polygons. It also touches on transformations, geometric solids, and non-Euclidean geometries. The problems, which the author culled from numerous sources cited in his footnotes, are well-chosen and interesting. Jacobs uses the problems to teach the reader concepts not covered in his exposition. However, despite beginning the text with a discussion of inductive and deductive reasoning, Jacobs does not teach the reader how to write proofs. In most of the proofs in the problem sets, the statements are given and the reader is required only to provide the reasons for the statements. There are few opportunities for the reader to write an original proof. Therefore, I recommend the book as a supplement rather than a text.
