A horizontal line is a line perpendicular to the vertical.
Vertical motion is the motion that is perpendicular to the ground.
Vertical angles can be supplementary angles if the lines are perpendicular and then both of the vertical angles would be 90 digress.
No. Up-down is vertical. Horizontal is perpendicular to vertical.

No, the horizon is horizontal. A vertical line is perpendicular to the horizon.
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).
