30.3.5 Distance Between Two Parallel Lines

Core idea

Two parallel rails stay the same width forever, so pick any point on one and measure straight across to the other.

Module goal. Study how lines relate to each other, judge their positions, find intersections, and compute distances, finishing the toolbox for lines.
