The thought of solving theorems or postulates leaves some students quivering in their boots. . . but not anymore! This must-have guide takes the pain out of learning geometry once and for all. The author demonstrates how solving geometric problems amounts to fitting parts together to solve interesting puzzles. Students discover relationships that exist between parallel and perpendicular lines; analyze the characteristics of distinct shapes such as circles, quadrilaterals, and triangles; and learn how geometric principles can solve real-world problems.

Like all titles in Barron's Painless Series, this book presents informal, student-friendly approaches to learning geometry, emphasizing interesting details, outlining potential pitfalls step by step, offering "Brain Tickler" quizzes, and more.
