Question

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

Answer 1

p = 2

r = 4

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.
