I'm a daily AutoCad user so I know the perpendicular snap well.  It causes a line you are drawing to snap to a target line such that the two lines are perpendicular.  I noticed that LibreCad doesn't have such a snap mode but there are work-arounds.

1) Where the target line is horizontal or perpendicular: before snapping the line endpoint to the target line, activate Snap On Entity and either Restrict Horizontal/Vertical then snap to the target line.  

2) Where the target line is sloped:  Use the "perp" command (Orthogonal Line) and then trim to tidy up.
