Expert Answer:

begin mathsize 16px style Find space the space vectors space AC space and space BD.
Take space dot space product space if space it space is space zero space then space vectors space are space orthogonal.

NOTE colon
There space is space some space error space in space the space question. space
Please space check space it. end style
