1. Lesson 3-1 Parallel Lines and Transversals

2. Ohio Content Standards:

3. Ohio Content Standards: Formally define geometric figures.

4. Ohio Content Standards: Recognize and apply angle relationships in situations involving intersecting lines, perpendicular lines and parallel lines.

5. Ohio Content Standards: Recognize the angles formed and the relationship between the angles when two lines intersect and when parallel lines are cut by a transversal.

6. Skew Lines

7. Skew Lines Lines that do not intersect and are not coplanar.

8. G F B A Name all planes that are parallel to plane AEF. H E C D

9. G F B A Name all segments that intersect AF. H E C D

10. G F B A Name all segments that are parallel to DC. H E C D
