Introduce algebraic proofs and properties needed for geometric proofs.

null

Proof: Use logic, facts and deductions to prove a statement true.

Reflexive Property: a=a

Symmetric Property: If a=b, then b=a. (Switch the order around the equal sign)

Transitive Property: If a=b and b=c, then a=c. (Comparing three values)

Addition and Subtraction Properties: Add or Subtract to both sides of the equation

Multiplication and Division Properties: Multiply or Divide both sides of the equation

Substitution Property: If a=b, then a may be replaced in a equation with b.

Distributive Property: a(b+c) = ab + ac
