In filmmaking, the 180-degree rule [1] is a basic guideline regarding the on-screen spatial relationship between a character and another character or object within a scene. The rule states that the camera should be kept on one side of an imaginary axis between two characters, so that the first character is always frame right of the second ...
One of the keys to maintaining screen direction is the 180-degree rule, which cuts a horizontal line through the frame. [3] Actors are then filmed from only one side of the axis, maintaining the orientation of the space for the viewer. [4] This can be manipulated specifically to create a shift in perspective.
Original - The 180° rule is a basic guideline in film making that states that two characters (or other elements) in the same scene should always have the same left/right relationship to each other. If the camera passes over the imaginary axis connecting the two subjects, it is called crossing the line.
A wingover is a maneuver used to provide a fast, 180 degree turn with a very small turn radius. It consists of a quarter loop into a vertical climb, letting the speed fall as altitude increases, and then a flat-turn over the top, diving to complete a quarter loop at the original altitude, but going in the opposite direction.

The bearing angle value will always be less than 90 degrees. [1] For example, if Point B is located exactly southeast of Point A, the bearing from Point A to Point B is "S 45° E". [ 3 ] For example, if the bearing between Point A and Point B is S 45° E, the azimuth between Point A and Point B is 135°.
In Australia, there is a special definition for a bend (or a horizontal bend) which is a connection between two tangent tracks at almost 180 degrees (with deviation not more than 1 degree 50 minutes) without an intermediate curve. There is a set of speed limits for the bends separately from normal tangent track. [5]
