The Shortest Distance Between Two Points
In the language of Geometry, distance is an absolute value. Given multiple and various points, to determine the shortest distance between these points, one way is to draw a perpendicular line connecting the points. Observing the magnitude of each segment, the two points that produce a perpendicular line has the shortest distance.
Which of the segment above produces the shortest distance? How do you call that segment? Which of the segment above produces the longest distance?
