What is the minimum number of skaters required to form a line in an artistic element?

To form a line in an artistic element in synchro skating, the minimum requirement is two skaters. This is because a line inherently involves a formation where skaters align themselves next to each other, creating a visual representation of unity and cohesion. With just one skater, it is not possible to depict a line; there must be at least a pair for the formation to be recognized and evaluated as such.

Using two skaters allows for the establishment of a straight line, showcasing their ability to skate in sync while maintaining appropriate spacing and alignment. This element also emphasizes teamwork and synchronization, which are vital aspects of synchro skating. A larger number of skaters may enhance the visual impact of the line, but the fundamental requirement for it to exist is met with just two skaters.
