Is AB and CD parallel?
First, we need to calculate the slope (m) of AB and CD
For AB:
So:
For CD:
So:
For Lines to be parallel, the slope must be equal:
i.e.
This condition is not true because:
For Lines to be perpendicular, the slope must be:
This implies:
<em>Hence, the lines are perpendicular</em>
