It is both perpendicular to the base and vertical.

∙ 12y ago'altitude' or perpendicular. If on line is the base (horizontal) line, then the line that is a 90 degrees to it is the perpendicular/altitude.
It is a line that is not at an angle of 90 degrees to the horizontal!
A vertical line at 90 degrees
Construct a perpendicular line that intersects a horizontal line at 90 degrees and then bisect the vertical line with the horizontal line will give an obtuse angle of 135 degrees because 90 degrees+45 degrees = 135 degrees
A line 90 degrees from horizontal is a plumb line.
A right angle which is 90 degrees
Right angles (90 degrees) will be formed.
A vertical angle is perpendicular to a horizontal base and equals 90 degrees
It goes up like this ----> l
It is the horizontal number line that intersects the y axis at 90 degrees on the Cartesian plane
It's the horizontal line on the Cartesian plane that meets the y-axis at the origin at 90 degrees.
Yes, but only if they are exactly vertical and exactly horizontal (90 degrees angular difference). For real-world examples, many vertical lines can be perpendicular to a single "horizontal" curved line at the points of intersection.
