True
You can see all the points equidistant
Horizontal
45o
perpendicular is a line drawn at an angle 90 to other given line
True
fuselage centerline is drawn at center of maximum height of the body alined horizontally but fuselage reference line is a zero-lift line of the wing-body of the airplane

It could be in reference to the "mythical" line drawn in the dirt by Col. William Travis at the Alamo. Those wishing to stay and fight were to step across the line. Those wanting to leave were to remain behind the line.
An angle is formed by at least three points of reference. The origin and two others in plain geometry. A line may be drawn from the point of origin and any other given point. Any other line may be drawn from the origin and any other point. The difference between these lines is referred to as an angle.
A circle is a line, drawn around a point in such a way that the line is always the same distance from the point. This distance is known as the 'radius' of that circle.
Because people ALWAYS misuse the word line. What is actually being drawn is a curve. This is one of my pet-peeves too. It bothers me fundamentally when people say "Straight-line" (redundancy) or "curved line"(oxymoron).
line-drawing
There is only one line (or line segment) that can be drawn between two distince points.
The sample letter with attention should be formal in nature and must have two addresses. The attention should be drawn to a given reference and duly signed.
The line is called a diagonal if it is drawn between two nonadjacent angles.
A normal line is the name of the line drawn perpendicular to the surface where a light ray strikes.
