KB10687 - What is the most efficient way, using the DK, to find out if a simple line ShapeArc (one part, two points) lies on the perimeter of a ShapePolygon?

Use the DK function TGIS_Shape.Relate to determine if a geometric relation between the shape and line is True. Refer to the DK Relation sample in DK sample set #4 for guidance.

TGIS_Shape.Relate uses the DE9IM array to define the relation. More about the TatukGIS support of the DE9IM model can be found in the DK Guide. (The DK Guide is incomplete, but there is a good description there of the DE9IM model.)
