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
To the core book!
Turn to page 75
Complete the proof of the linear pair theorem together
Vertical Angles Theorem
What are vertical angles again?
Vertical Angles Theorem: Vertical angles are congruent.
Proof of the Vertical Angles Theorem
KNOW THIS PROOF FOR YOUR EXAM!
Turn to page 76
We will prove it together
Add these two theorems to your notes
Congruent Supplements Theorem
Congruent Complements TheoremSame thing as supplements theorem,
only with complementary angles.
