1. Section 2-6: Geometric Proofs Rigor – prove and apply the Vertical Angles Theorem and the Linear Pair Theorem Relevance – These simple proof gives you the opportunity to practice your logic and proof building skills

2. To the core book! Turn to page 75 Complete the proof of the linear pair theorem together

3. Vertical Angles Theorem What are vertical angles again? Vertical Angles Theorem: Vertical angles are congruent.

4. Proof of the Vertical Angles Theorem KNOW THIS PROOF FOR YOUR EXAM! Turn to page 76 We will prove it together

5. Add these two theorems to your notes Congruent Supplements Theorem Congruent Complements Theorem Same thing as supplements theorem, only with complementary angles.
