**+27 Mm Interiors References**. For point/point inputs the relationship is always false, since points do not have a boundary. Returns true if a and b intersect, but their interiors do not intersect.

For point/point inputs the relationship is always false, since points do not have a boundary. Equivalently, a and b have at least one point in common, and the common points lie in the intersection of their boundaries. Returns true if a and b intersect, but their interiors do not intersect.

### Equivalently, A And B Have At Least One Point In Common, And The Common Points Lie In The Intersection Of Their Boundaries.

Returns true if a and b intersect, but their interiors do not intersect. In mathematical terms, this relationship is expressed as: For point/point inputs the relationship is always false, since points do not have a boundary.
