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.
Examples of horizontal lines in the real world include the horizon where the sky meets the land or sea, the straight line of a calm lake's surface, the boundary between the wall and floor in a room, and the straight line of a ruler placed flat on a table. Horizontal lines are parallel to the horizon and perpendicular to vertical lines.
Perpendicular
A line is perpendicular to a plane when it is perpendicular on two lines from the plane
The horizon runs horizontal. Perpendicular to that is VERTICAL.
No, the horizon is horizontal. A vertical line is perpendicular to the horizon.

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 refers to a direction that is oriented up and down, perpendicular to the horizon. In contrast, horizontal refers to a direction that is oriented across, parallel to the horizon. Therefore, vertical is specifically associated with the up-and-down orientation.
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).
