This is vital. It provides the solutions to all the exercises, including step-by-step guidance on how to set up and complete the two-column geometric proofs.
Congruence, similarity, and the Pythagorean theorem.

: An excellent modern companion to help visualize the "Seeing" part of Jacobs' philosophy.
Jacobs introduces concepts through cartoons (like B.C. and The Wizard of Id ), optical illusions, photography, and historical anecdotes. This shows students why geometry matters before diving into the math. The text has evolved over time, but its

The —an ingenious feature of the book—begin with Set I, which reviews previous concepts, advance to Set II, which applies new material, and culminate in Set III, which provides more challenging problems and puzzles for advanced students.
