Makes the first selected line perpendicular to the second selected line.

1. Start with two lines. Activate the Perpendicular constraint and select the line you want to be made perpendicular.
   
2. Select the line to which you want the first line to be perpendicular.
   
3. If you edit either line, the perpendicular constraint will be maintained.
    
    If you apply this constraint to lines that do not intersect . . .
   
   . . . the perpendicular constraint symbol will appear along the extension of one or both lines.
