Line L is parallel to line n.

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 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: -|

A horizontal line is a line perpendicular to the vertical.

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.

The perpendicular postulate states that if there is a line, as well as a point that is not on the line, then there is exactly one line through the point that is perpendicular to the given line.

"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.

perpendicular bisector

A perpendicular line is 90 degrees. Anything less or more is not perpendicular.

If the line has a slope of 2, then the perpendicular line has a slope of -1/2. The slope of a perpendicular line is the negative reciprocal. Another example would be if the slope of a line is -1/4, then the slope of the perpendicular is 4.

The perpendicular bisector of a line segment AB is the straight line perpendicular to AB through the midpoint of AB.

A perpendicular bisector goes through the median of the line while a perpendicular line can be anywhere on the line as long as it is at a 90 degree angle.

The line perpendicular to a barrier is called the normal.

perpendicular is a line drawn at an angle 90 to other given line

A plum-line is used to mark a line that is perpendicular to the ground.

no an addition sign is a perpendicular line segments

A perpendicular line intersects another line at 90 degrees.

The negative reciprocal of the slope of the line to which it is perpendicular.

The slope of a perpendicular line is not defined.

The difference between a perpendicular line and a parallel line is that a perpendicular line crosses or joins, while a parallel line doesn't touch at all.

Start with a line, L1. Draw a line perpendicular to it, L2. Next draw a line perpendicular to L2, but not the same as L1. This last line will be parallel to L1.

basically the reciprocal of the original lines gradient is going to be the gradient for the perpendicular line (remember the signs should switch). For example if i had a line with the gradient of 3, then the gradient of the perpendicular line will be -1over3. But if the line had the gradient of -3, then the line perpendicular to that line will have the gradient 1over3.

The line perpendicular to a surface at a point is called the normal
