A single slash perpendicular to the line is used to show it is congruent. In other words, if two segments are congruent they would both have a single slash through them, but if you have multiple pairs, each separate pair would have its own unique number of slashes (1,2,3...).
Since I can't attach illustrations here (can I?), I can describe one. If two congruent and parallel triangles have vertices joined by line segments, the line segments described will mark the boundaries of a solid.
