2 vertical angles must equal up to 180 degrees to be considered supplementary. The equation given is not supplementary because the angles add up to 168.
The characteristics of these geometric figures create: 1. Parallel lines are lines in the same plane that will never intersect and also if they are in different planes, those lines will never intersect too. 2. While perpendicular lines are two lines that will meet at a 90-degree angle or right angle.
