1. Exploring Algebraic and Geometric Relationships
Section 1.3 Students till be able to identify and prove relationships between pairs of angles among intersecting lines.

2. 1.3.1 What is a relationship
Theorem – proving a conjecture Go through 1-69 and 1-69, come up with definitions (descriptions) for the following and make sure you understand each of the problems associated with them Angle Pair Relationships Complementary Angles Supplementary Angles Straight Angles Linear Pair Vertical Angles Congruent Angles

3. Proofs of Vertical ANgles
Investigation 1-70 and 1-71 Work through and solve 1-72

4. Area models of Products and Sums
Using Algebra Tiles How did we do this in the previous section Length and width are expressions Area is the product of the expressions Perimeter is the sum Area model to help with multiplication (box method)

5. Homework
Pg through 1-80

6. 1.3.2 and 1.3.3 What is the Relationship 2
Angle Pair Relationships with parallel lines and transversals Investigate 1-81 Investigate 1-93 Parallel Lines Transversal Corresponding Angles Alternate Interior Alternate Exterior Same Side Interior

7. Proving the Conjectures
