Master geometry at your own pace. The ultimate summer preview and school-year companion.

Scaffolded for independent learning, Summit Math Geometry eliminates a common source of frustration by focusing on intuitive reasoning and active problem-solving rather than formal proof-writing. Across 8 comprehensive units, students discover not just what to do, but why it works.
 
Why Choose the Summit Math Approach?
 
Active Learning: Each lesson actively builds intuition through guided problem-solving.
Comprehensive Coverage: A full year of high school geometry spanning 250 pages, from the basics of angles, parallel lines, & polygons to the more advanced topics of trigonometry, circles & surface area.
1,500 Exercises: From foundational skills to challenging applications, students get the repetition and depth needed for mastery.
Step-by-Step Answer Key: Clear, detailed solutions help students learn from mistakes and confidently work independently.
8 Page-Mapped Unit Tests: Each test has an Answer key with an index that maps test questions back to specific pages, making it easy to identify concepts that need more review.
Classroom-Tested Authority: Aligned with standard high school geometry curricula and written by a teacher with 20+ years of classroom experience.

A Better Way to Learn Geometry
Many students struggle when Geometry is taught as a list of rules to memorize. Summit Math Geometry takes a different approach, helping students enjoy the journey as they actively engage in learning each concept and become better problem-solvers.
