In this job, you can determine the coordinates of the perpendicular projection of a point to a line (foot of the perpendicular projected from the entered point to a line).
Enter the coordinates of the start and end points of the line and the coordinates of the adjusted point in the calculation window. The program will project a normal line from the adjusted point to the entered line, calculate the coordinates of the intersection of the normal line and the entered line (foot of the perpendicular), and calculate the distance of the projected point from this intersection (distance of the point from the entered line).
The calculated foot of the perpendicular can be transferred to the coordinate list in the usual way.
