The horizon runs horizontal. Perpendicular to that is VERTICAL.
In a Euclidean plane, only one.
It's the height.
The transverse plane is perpendicular to the longitudinal axis.

I believe the answer is "perpendicular line". Forgive me if I'm wrong :)
Two lines are said to be perpendicular when they are at right angles. That means that the angle between them is 90 degrees.There are other meanings of perpendicular; for example, a line is said to be perpendicular to a plane when it is perpendicular to EVERY line of the plane that goes through the intersection.
NO. Perpendicular lines in the same plane alwaysinthersect.
A line that is perpendicular to the segment of a plane and passes through the midpoint.
No
No, that is not true.
Yes they are. It's a postulate: In a plane two lines perpendicular to the same line are parallel.
orthographics means line is perpendicular to the view plane,while oblique means line is not exactly perpendicular to the view plane.
The horizon runs horizontal. Perpendicular to that is VERTICAL.
There's no such thing as one perpendicular line. "Perpendicular" tells the relationship between two lines, or between a line and a plane. Two lines are perpendicular if they form a 90-degree angle where they cross.
The perpendicular to a plane mirror is a line that is at a 90-degree angle to the mirror's surface. It is important for understanding the reflection of light rays off the mirror's surface, as the angle of incidence is equal to the angle of reflection with respect to this perpendicular line.
1. Top view is directly over the front view. 2. Side view is inline horizontally with either top view or front view. 3. A line parallel to a plane of projection will be projected on that plane as a line. 4. A surface parallel to a plane of projection will be projected on that plane 5. A line perpendicular to a plane of projection will be projected on that plane as a point. 6. A surface perpendicular to a plane of projection will be projected on that plane as line.
