A vertex-face assignment for plane graphs

For any planar straight line graph (PSLG), there is a vertex-face assignment such that every vertex is assigned to at most two adjacent faces, and every face is assigned to all its reflex vertices and one more incident vertex. The existence of such an assignment implies, in turn, that any PSLG can be augmented to a connected PSLG such that the degree of every vertex increases by at most two.
