IN MATH: 1. adj. on a plane, lines which never intersect, lines which have the same slope and share no points; in a polygon, sides which are segments of lines which never intersect. 2. adj. in 3-space, lines which though in the same plane never intersect; in 3-space, planes which never intersect. EX. Parallel lines have the same slope and are written as a system of inconsistent equations. 3. adj. on a sphere, circles which never intersect and which each line on planes perpendicular to the line drawn through their centers.

IN ENGLISH: 1. adj. same distance apart. EX. Though railroad tracks appear parallel when you stand with one foot on each track, in the distance they do not appear parallel. 2. adj. on a globe, circles which line on planes perpendicular to a diameter of the globe. Ex. Latitude lines are parallel to the equator. At what latitude and longitude do you live?

APPLICATION: See list 140

1. Name the quadrilateral with 2 sets of parallel sides.

2. Give the equation of a line parallel to y = 3x + 2 and y = 3x -1.
