We study the geometry of germs of singular surfaces in whose parametrisations have an -singularity of -codimension less than or equal to 3, via their contact with planes. These singular surfaces occur as projections of smooth surfaces in to . We recover some aspects of the extrinsic geometry of these surfaces in from those of the images of their projections.
