3.1: Parallel Lines and Transversals Name: _____________________________ Warm-up: Determine if the real-world examples show lines that are parallel, perpendicular or neither.

¾ Describe how the two examples above that are neither are different from parallel and perpendicular lines.

Vocabulary: Parallel: coplanar lines that do not intersect

x Real-life examples: ___________________________________________________________________ Perpendicular: lines that intersect to form right angles

x Real-life example: ____________________________________________________________________ Skew: noncoplanar lines that do not intersect x Real-life example: ____________________________________________________________________

Practice: Think of each segment in the diagram as part of a line. There may be more than one correct answer.
