What must skaters do in the back-to-back approach during an intersection?

The requirement for skaters during the back-to-back approach in an intersection is to connect with a simple hold. This is essential for ensuring that the skaters maintain proper formation and synchronization while navigating through the intersection. The simple hold allows for clear communication and stability among the skaters, enabling them to effectively execute the maneuver without losing their positions or disrupting the flow of the performance.

Maintaining visual contact among all skaters is important for coordination but does not specifically address the technique used during the intersection. Likewise, skating in a line formation and executing complex movements together may be relevant to other scenarios but do not directly apply to the specific mechanics of the back-to-back approach in this context. Thus, while visual contact and maintaining formations are important overall, connecting with a simple hold is the action that specifically supports the execution of the back-to-back intersection correctly.
