Parallel and perpendicular lines review

Review the basics of parallel and perpendicular lines.  Identify and draw parallel and perpendicular lines in some practice problems.  

What are perpendicular lines and parallel lines?

Perpendicular lines are lines that meet at right angles.
Two lines that meet at right angles.
Parallel lines are always the same distance apart from each other — no matter how far they are extended, they will never meet.
Two lines that will never cross.
