All compulsory figures had the following: circles, curves, change of foot, change of edge, and turns. The circle, the basis of all figures, was performed on both its long and short axes. Skaters had to trace precise circles, while completing difficult turns and edges. Most figures employ "specific one-foot turns not done in combination with other one-foot turns". Each figure consisted of two or three tangent circles. Each circle's diameter had to be about three times the skater's height, and the radii of all half-circles had to be approximately the same length. Half-circles and circles had to begin and end as near as possible to the point in which the long and short axes intersected. The figure's long axis divided it longitudinally into equal-sized halves, and the figure's short axes divided the figures into equal-sized .
