LOGIC

Geometry is an orderly approach to solving problems. In this unit you will examine inductive reasoning, statements of logic, and deductive reasoning. Through these formal approaches to making logical decisions, you will begin to understand that mathematical conjectures are based on observations and mathematical proofs are based on detailed statements of logic.
