... and described by their transverse directions. A corner, as shown in Fig. 1 , is a convex arc that tangentially joins two intersecting sides at an external angle of more than 180°. Corners serve to join the sides of a rib or boss with its peak or land. A full-rounded or full-radiused top of a rib is...
