perpendicular (comparative more perpendicular, superlative most perpendicular)

1. (geometry) At or forming a right angle (to).
   • 2012 March 1, Henry Petroski, “Opening Doors”, American Scientist, volume 100, number 2, page 112-3: 

     A doorknob of whatever roundish shape is effectively a continuum of levers, with the axis of the latching mechanism—known as the spindle—being the fulcrum about which the turning takes place. Applying a force tangential to the knob is essentially equivalent to applying one perpendicular to a radial line defining the lever.

   In most houses, the walls are perpendicular to the floor.
