I have a program that runs in Excel. Basically I have a set of points with co ordinates X and Y. The program I have lists all the lengths between all pairs of points, and then all the angles from picking all sets of 3 points. The idea is to look at the angles and lengths to see if the points are random or not. I am looking to extend this, and someone may be able to do this by altering the program I have. I want to be able to list all possible triangles, 4, and 5 sided figures with the points, and all the angles and sides each of these polygons would have. I also want the program to list the orientiations of each line drawn between pairs of points, like a compass reading 0 to 360 degrees.
I can send the program for you to look at.
