Answer:
12. parallel, 13. perpendicular
Step-by-step explanation:
Find the slope of both lines
AB:(6-3)/(2--2)=3/4
CD:(3-0)/(3--1)=3/4, the slope is the same so the lines are paralell
2. DO the same thing
AB:(4-2)/(5-0)=2/5
CD:(3-8)/(3-1)=-5/2, the slopes are opposite inverses so they are perpendicular
