2.4 Algebraic Reasoning

EQ: How can you show your algebraic reasoning in a 2-column proof format?

Review algebraic properties of equality (addition, subtraction, multiplication and division) along with substitution and the distributive property.  Additional properties covered include reflexive, symmetric and transitive (for algebraic equations, segments and angles).

Prep work:  p96(3-6, 13-14, 19-42, 46-47)
