What is the shortest between a point and a straight line?
The vertical line between a point and a straight line is the shortest.

Expand:

Between a point and a straight line, the vertical line is the shortest. Between two points, the line segment is the shortest. Vertical line segment is a noun in mathematical theory. The length of the vertical section from any point outside a straight line to this straight line is called the distance from this point to this straight line.

From the vertical nature: the vertical line segment drawn from a point outside the straight line is the shortest, and its length is called the distance from that point to the straight line, so the answer is that the vertical line segment from that point to the straight line is the shortest.

Of all the connecting lines from point to straight line, (vertical line) is the shortest; The distance between (parallel lines) is equal everywhere. If two straight lines intersect (at right angles), they are (perpendicular to each other), and one of them is called the (perpendicular) of the other.
