Abstract
An interconnectable panel has a pair of surfaces on a lateral edge that adjoins a second pair of surfaces on a complementary lateral edge of another panel when the two panels are interconnected. The edge profiles are such that the first pair of adjoined surfaces has a cross-sectional contour in the shape of a segment of a circle. The circle has a center lying in the upper sections of the connected lateral edges. The circle also has a radius measured from the center to the first pair of adjoined surfaces. The second pair of adjoined surfaces is spaced away from the center of the circle by a distance greater than the radius. That distance increases in a direction away from the first pair of adjoined surfaces.
