2. Objective  I can solve problems and write proofs involving the Transitive and Substitution Properties.

3. Theorem: Transitive Property  If two angles (or segments) are congruent to the same angle (or segment), then they are congruent to each other.  Example: If

4. Theorem: Transitive Property  If angles (or segments) are congruent to congruent angles (or segments), then they are congruent to each other.  Example:

5. Substitution Property  Replace one angle with another.  Use with complementary and supplementary angles.  Example: If is comp to and then is comp to.
