Draw a straight line and with compass mark off two joined arcs above and below the line and then join the arcs together which will produce a perpendicular line.
You construct a line perpendicular to the original and then a line perpendicular to this second line.
Points: (5, -1) and (2, -5) Slope: 4/3 Perpendicular slope: -3/4
perpendicular line segment (apex)
~APEX~ A parallel line through a point not on the line
A perpendicular bisector.
There is no name for it except "A line perpendicular to a line segment and passing through its midpoint".
Perpendicular lines passing through a point are at right angles to each other.
Perpendicular to a line passing through the center of the Earth.

It does not have a specific name.
The slope of the perpendicular to the line passing through P1(3,6) and P2(5,1) is 2/5. Note: the slope of the original line is (change in y)/(change in x), yielding -5/2. The slope of the perpendicular is the negative reciprocal, 2/5
You can construct a parallel to a line through a point not on the line. (perpendicular line segment)
You construct a line perpendicular to the original and then a line perpendicular to this second line.
You construct a line perpendicular to the original and then a line perpendicular to this second line.
y=-x
Infinite. The line is perpendicular to the ordinate.
