The No-Trig Geometry Book I: Think Outside the Sine
Discover the beauty of geometry—without relying on trigonometry.
The No-Trig Geometry Think Outside the Sine invites readers to explore geometry in its purest form.
Designed for high school students, teachers, and math enthusiasts alike, this book offers a refreshing return to classical reasoning—where elegant geometric insight replaces mechanical calculation.
Inside, you’ll find 81 carefully crafted problems, divided into three
Chapter 1: 27 angle problems
Chapter 2: 27 length problems
Chapter 3: 27 area problems
Each problem can be enjoyed twice—once by solving it with trigonometric methods, and again by uncovering a purely geometric approach that reveals the deeper structure of the figure.
Every solution is presented with clarity and creativity, emphasizing geometric relationships, symmetry, and logical reasoning over formula memorization.
Whether you’re a student preparing for exams, a teacher looking for engaging classroom material, or an adult who simply loves the elegance of geometry, this book offers a double
the challenge of problem solving—and the joy of rediscovering geometry beyond trigonometry.
