Vertical lines in space run perpendicular to the horizon. The very definition of perpendicular requires that the lines be at right angles to the horizon, so all lines that meet that definition are perpendicular.
The horizon runs horizontal. Perpendicular to that is VERTICAL.
No, the horizon is horizontal. A vertical line is perpendicular to the horizon.
Perpendicular
A line is perpendicular to a plane when it is perpendicular on two lines from the plane
The foot of a perpendicular is the lowest part of the perpendicular [Kinda like the feet of people]||||_____^ This is the point where the foot of the perpendicular meets the line.
The horizon runs horizontal. Perpendicular to that is VERTICAL.
No, the horizon is horizontal. A vertical line is perpendicular to the horizon.
vertical
y=0, x=R
33 degrees perpendicular to the horizon
It is a vertical line.
A circle through the Earth's sphere perpendicular to the observer's latitude
Vertical is defined as the direction or position that is perpendicular to the plane. Horizontal is defined as to be parallel to the horizon.
Draw a line perpendicular to the horizon axis, that goes from the top vertex, to a line that is the continuation of the base.
Vertical lines are lines that are drawn / made perpendicular to the horizon. In other words, they go "ceiling to floor", not "wall to wall" or "corner to corner."
There is no such thing as exactly vertical because either it is vertical or it is not. You cannot have approximately vertical - it is not vertical, then. Vertical means at 90 degrees to the horizon (or horizontal).
Receding lines converge into vanishing points. If you stared at railroad tracks leading away from you, as they approached the horizon, they'd appear to meet. They disappear/converge into the vanishing point.
