Parallel and Perpendicular Lines Chapter 3 Parallel and Perpendicular Lines
3-1 Parallel Lines and Transversals In this section we will identify the relationships between two lines or two planes. We will name angles that are formed by a pair of lines and a transversal.
Vocabulary Parallel Lines Parallel Planes: Coplanar lines that do not intersect. Parallel Planes: Two planes that do not intersect.
Vocabulary Skew Lines Are not parallel Do not intersect Do not line in the same plane.
Vocabulary Transversal A line that intersects two or more lines in a plane at different points. Transversal
