Perpendicular because their slopes or gradients are 5 and -1/5 respectively
parallel lines
A perpendicular line is a line that creates two 90 degree angles at the line, segment, etc. that it intersects. Parallel lines are two lines that never intersect. Perpendicular lines cross at right angles (+) Parallel lines will never meet, no matter how far they are extended (=)
perpendicular bisector
In a plane, there are infinitely many lines that can serve as perpendicular bisectors of a given segment. The unique perpendicular bisector of a segment is a specific line that divides the segment into two equal parts at a right angle. However, any line parallel to this unique bisector, at any distance, can also be considered a perpendicular bisector if it intersects the segment at its midpoint. Thus, while the unique perpendicular bisector exists, an infinite number of lines can be drawn parallel to it.

Parallel
You can construct a parallel to a line through a point not on the line. (perpendicular line segment)
Neither: because one line, by itself, can be neither parallel or perpendicular. These characteristics are relevant only in the context of another line (or lines). The given line is parallel to some lines and perpendicular to others.

A perpendicular line is a line that creates two 90 degree angles at the line, segment, etc. that it intersects. Parallel lines are two lines that never intersect. Perpendicular lines cross at right angles (+) Parallel lines will never meet, no matter how far they are extended (=)
perpendicular bisector
It's called a perpendicular bisector of the line segment.
