A straight line that intersects another straight line at 90 degrees
The slope of a perpendicular line is not defined.
It could be referring to a perpendicular line
Go get a math book and look it up, stop being lazy.
Perpendicular means that two lines intersect like an X but its just perpendicular
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).
There is arrows on both sides of the line
In geometric terms, one line is said to be perpendicular to another when their angle of intersection is 90°
It means a line that intersects with another line. Where as parallel would be a lines that do not intersect, ever.
X (or Y) = (one value)
"Perpendicular" means at an angle of 90° to a given line, plane, or surface.
Type your answer here... two dots connected by a line
a line with arrows on each end. it must have points in between the two arrows
