begin mathsize 16px style Find space slope space of space AB comma BC comma CD space and space AD. If space slopes space of space the space lines space are space equal space then space they space are space parallel. Also space if space product space of space the space slopes space of space the space lines space is space minus 1 space then space they space are perpendicular. Using space this space show space that space it space is space straight a space square. Then space find space side space of space straight a space square space and space diagonal. end style
