## Geometry Course Outline

The Geometry course introduces the nature of the proof and the use of deductive and inductive reasoning. Students will learn how to work with theorems and geometric constructions during the course of their study and will cover some of the basics of trigonometry. While Jurgensen and Brown on Geometry is the primary textbook, students will also be studying proofs based on Euclid and many of the chapters will track Euclid’s line of proof and deductive reasoning. This course uses Geometry by R. Jurgensen, R. Brown, and J. Jurgensen.
