Geography.kif 837-850

If a region is an instance of uniform perimeter area and an object is a part of the inner boundary of the region and another object is a part of the outer boundary of the region and the distance between the object and the other object is a length measure and a third object is a part of the inner boundary of the region and a fourth object is a part of the outer boundary of the region and the distance between the third object and the fourth object is another length measure,
then the length measure is equal to the other length measure

consequent

(=> (instance ?AREA UniformPerimeterArea) (exists (?WIDTH) (distance (InnerBoundaryFn ?AREA) (OuterBoundaryFn ?AREA) ?WIDTH)))	Geography.kif 825-828	If a region is an instance of uniform perimeter area, then there exists a length measure such that the distance between the inner boundary of the region and the outer boundary of the region is the length measure
(=> (instance ?REGION Region) (superficialPart (OuterBoundaryFn ?REGION) ?REGION))	Geography.kif 815-817	If a region is an instance of region, then the outer boundary of the region is a superficial part of the region
