In triangulation, how are the instrument tips arranged?

• A. At the same angle to target tissue.
• B. At different angles to create a triangle around the target tissue.
• C. One instrument only is used.
• D. The camera is inside the target tissue.

Answer: (B)

Triangulation means arranging the instrument tips at different angles to form a triangle around the target tissue. This setup allows each instrument to approach from its own direction, so one can retract while another dissects and the camera views from a separate angle. That geometry improves depth perception, maneuverability, and control while reducing instrument collisions. If all tips were at the same angle, access would be limited and visualization and manipulation would be poor; using only a single instrument eliminates the needed countertraction; and envisioning the camera inside the tissue isn’t how laparoscopic visualization is achieved.
