Geometry Wed 10/15/14 Warm-ups….Complete Guided Reading Slide Discussion/Notes/Guided Practice – Section 2.6 Algebraic Proofs Homework: – Algebraic Proofs Practice Worksheet After this section, you will be able to: 1. Use algebra to write two-column proofs 2. Use properties of equality in geometry proofs Success Criteria: Q&A, Guided Practice, Homework Guided Reading – pg 94 Property Definition Example Reflexive Symmetric Transitive Addition Property of Equality Subtraction Property of Equality Multiplication Property of Equality Division Property of Equality Substitution Distributive Property Please look at example 1 to see how these properties are used to JUSTIFY WHY the problem can be solved. Please read Pg. 95 2. What is a two-column proof (also called a formal proof)? 3. Copy Example 2 into your notes. 2-6 Algebraic Proofs Pg. 94 What is deductive reasoning? Reasoning that uses facts, definitions, and other known information. What is inductive reasoning? Reasoning based on examples that you have already seen. Solve the following problem: 5x 7 42 Why are you allowed to do those steps? How do you know they work?
