6-4 Angle Pair Relationships
Ex 2:
Step 1: What type of angles are these? Vertical Angles
Step 2: What do we know about vertical angles?
Vertical angles are congruent (have same measurement).
b = 32°
Ex 3:
Step 1: What type of angles are these? Complementary Angles
Step 2: What do we know about complementary angles?
Two angles whose sum = 90°
Step 3: Write and Algebraic Equation and solve
