Lesson 3-1 Parallel Lines and Transversals

Ohio Content Standards:

Formally define geometric figures.

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

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.

Skew Lines

Lines that do not intersect and are not coplanar.

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

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

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

Name all segments that are skew to AD. B H G F E D C A

Transversal

A line that intersects two or more lines in a plane at different points.
