what are the smallest values of p and r that satisfy the definitions for parallel lines and perpendicular lines?

Answer:
p = 2
r = 4
Step-by-step explanation:
If you're doing parallel it needs to be like "side by side." The least you can do is 2 because you'll need at least one other line to be beside the original.
Perpendicular lines are intersecting, so if you intersect them as a plus sign, you'll make at least four right angles.
