Perpendicular lines = Right Angles, thus any right angle related things work, and you know the angle of one of the 3 (90 degrees) so the perpendicular line as a slope of 90 minus the the angle of the undefined:
Since the angles of a triangle must add to 180
Undefined + Perpendicular + Right Angle (90) = 180
Or something like that... been a while since I did geometry... hope this helps

A line with an undefined slope is a vertical line and so a line that is perpendicular to it is a horizontal line. In the coordinate plane, that would be a line with the equation y = c (for some constant c).
A slope is 0 if it is a straight horizontal line. A slope is undefined if it is a straight vertical line.
Slope of a line = m slope of perpendicular line = -1/m
The slope of a line perpendicular to one with a slope of m is -1/m.
0
Vertical lines always have an undefined slope. Slope for y = f(x) is given by :slope = dy/dxdx is zero at any point along a vertical line, making the slope undefined along a vertical line.
slope is infinite.as slope=tan a.here a=90.
No, they are perpendicular.
A vertical line has an undefined slope.
No, the slope of a horizontal line is 0. The slope of a vertical line is undefined.
if slope is given as m then perpendicular slope is -1/m (negative inverse)
An undefined slope is just a line straight down. The slope is undefined.
No. The slope of a horizontal line is zero. The slope of a vertical line is undefined.
An undefined slope is vertical.
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.
A slope is 0 if it is a straight horizontal line. A slope is undefined if it is a straight vertical line.
The equation of a line with an undefined slope is x = a.
zero is horizontal, undefined is vertical
