1. OH YEAH! Its Chapter 3 Time

2. Section 3.1 Parallel Lines

3. Types of Lines • Perpendicular – lines that form right angles • Intersecting – lines that share a point • Parallel – lines that do not intersect and are in the SAME plane • Skew – lines that do not intersect and are NOT in the same plane

4. When are lines perpendicular?

5. When are lines parallel?

6. Draw two lines. • Add another line that intersects both lines. • What is a transversal? This is a TRANSVERSAL

7. Name the transversal b y e
