I don't know if this meets your needs, but the easiest way is to create a clone [alt+d] and then rotate the clone through 90 degrees [ctrl+[]. Manipulating the parent shape updates the perpendicular clone.
I was wondering if rotations centers could be set independantly, but it seems that when orginal is rotated, its clones undergoes a rotation relative to original's rotation center and not to it's own rotation center.
Beginners' Questions Creating perpendicular lines

Hello,
How can I create 2 perpendicular lines?
How can I constraint a line to be perpendicular to another one?
The lines can be at any orientation (not specifically horizontal or vertical)...
