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

Page 2: Section 2-6: Geometric Proofs Rigor – prove and apply the Vertical Angles Theorem and the Linear Pair Theorem Relevance – These simple proof gives you

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.

Page 4: Section 2-6: Geometric Proofs Rigor – prove and apply the Vertical Angles Theorem and the Linear Pair Theorem Relevance – These simple proof gives you

Proof of the Vertical Angles Theorem

KNOW THIS PROOF FOR YOUR EXAM!

Turn to page 76

We will prove it together

Page 5: Section 2-6: Geometric Proofs Rigor – prove and apply the Vertical Angles Theorem and the Linear Pair Theorem Relevance – These simple proof gives you

Add these two theorems to your notes

Congruent Supplements Theorem

Congruent Complements TheoremSame thing as supplements theorem,

only with complementary angles.
