It is a vertical line.
The line that forms a 90 degree angle with any other line is called "perpendicular" or "orthogonal" to the other line.but u can call it right angled

It is called a perpendicular bisector.
If the horizon is on a level line of sight, a vertical line directly above the observer forms an angle of 90 degrees. 55 degrees would be quite high, being above 45 degrees.
Perpendicular Bisector
