A line is perpendicular to another line when it is at an angle of 90° to the other line. + (that plus sign is an example of a perpendicular line)
their slopes are negative reciprocals.
A line is perpendicular to a plane when it is perpendicular on two lines from the plane
A perpendicular line is one that is at right angle to another - usually to a horizontal line. A perpendicular bisector is a line which is perpendicular to the line segment joining two identified points and which divides that segment in two.
A sole line can't be perpendicular. To be perpendicular, a line has to meet with another line, to form right angles on either side. Perpendicular is the exact opposite of parallel. Parallel: = Perpendicular: -|
"Perpendicular" is a straight line at a 90 degree angle from a line it touches or intersects. There is no line "straighter" than a perpendicular line, that I know of.
Yes. There can be a line perpendicular to the given line at every point on it, and you know how many different points there are on it ...
That would depend on its slope which has not been given.
Perpendicular line.
A right bisector of a line segment, is better know as a perpendicular bisector. It is a line that divides the original line in half and is perpendicular to it (makes a right angle).
A horizontal line is perpendicular to a vertical line.
A line is perpendicular to another line when it is at an angle of 90° to the other line. + (that plus sign is an example of a perpendicular line)

A horizontal line is a line perpendicular to the vertical.
