coplanar lines that don't intersect
lines that don't intersect that are not coplanar
a line that intersects 2 or more lines in a plane at different points
Corresponding Angles Postulate
If 2 parallel lines are cut by a transversal, then each pair of corresponding angles is congruent
Perpendicular Transversal Theorem
In a plane, if a line is perpendicular to one of the 2 parallel lines, then it is perpendicular to the other.

quantity changing over time
IF 2 lines in a plane are cut by a transversal so that corresponding angles are congruent, then the lines are parallel
If a given line and a point not on the line, then there exists exactly one line through the point that is parallel to the given line.
