What is the 180-degree rule and why is it important for continuity?

• A. Keep the camera on one side of an imaginary axis between characters to preserve consistent screen direction and spatial relations.
• B. Always shoot with the camera at eye level.
• C. Maintain a 180-degree arc when moving the camera.
• D. Cut only on action to ensure continuous motion.

Answer: (A)

The idea being tested is keeping the camera on one side of an imaginary line that runs between characters, so the audience sees a consistent left–right orientation and spatial relationship across shots. This axis of action helps preserve where everyone and everything are in the scene, preventing the perception that a character has switched sides or moved through space in an impossible way when you cut between angles. Crossing that line with the camera can make the geography of the scene feel scrambled and confusing, which hurts continuity.

The correct description matches this concept exactly: stay on one side of the axis between characters to maintain consistent screen direction and spatial relations. If you don’t, the relative positions flip from shot to shot, and the scene loses its clear sense of space.

The other ideas aren’t about this rule. Shooting at eye level concerns camera height, which affects perspective but not the directional continuity. Maintaining a 180-degree arc focuses on camera movement around a subject rather than the viewer’s orientation across cuts. Cutting only on action relates to matching movement across cuts, a separate technique for preserving flow, but it doesn’t define the 180-degree rule itself.
