Answer:
Yes
Explanation:
If the diagonals are perpendicular, then the slope of AC will be the opposite reciprocal of the slope of BD.
The slope of AC is:
m = (3 − 3) / (6 − 0) = 0
The slope of BD is:
m = (0 − 6) / (3 − 3) = undefined
The opposite reciprocal of 0 is undefined, so the diagonals are indeed perpendicular.
Specifically, AC is horizontal and BD is vertical.
