perpendicularly
Crossing at ninety
At right angles to a surface or line: The nail was driven perpendicularly into the board.
More loosely, straight up and down, vertically: The cliff rose perpendicularly from the sea.
The word is formal and somewhat awkward; speakers often prefer alternatives like straight up or at a right angle.
