Touch returns t (TRUE) if none of the points common to both geometries intersect the interiors of both geometries; otherwise it returns f (FALSE). At least one geometry must be a linestring, polygon, multilinestring, or multipolygon.

The denominators for the equations for ua and ub are the same. ... If the denominator for the equations for ua and ub is 0 then the two lines are parallel. ... The equations apply to lines, if the intersection of line segments is required then it is only necessary to test if ua and ub lie between 0 and 1. Whichever one lies...
