How do I create some code that will check angles and select the next point to draw a line to based on smallest angle?

Hi,
I need to create the simplest code that will check the angles between a line connecting one central point and another and a line from the same initial central point to a triplet endpoint. I need the code to be able to select the correct central point to draw a line to based on smallest angle (see attached pics). Attached are the two files that contain the coordinates for the central points (f_points) and the endpoints (Triplets): The files are (1) F_points.mat (2) Triplets.mat

Below is an image which gives an idea of what is needed:

The main requirement is that the lines connecting the neighboring central points must make the smallest angle with one of their corresponding endpoints.

Distance could be used to narrow down to a specific vicinity. Then, the angle that a potential line (between central points) would make with another line (from the the source central point to the corresponding endpoint) could be used to verify a line is correct. Is that what you did?

Here is some start
What about these?

I see what you are pointing out there but, as mentioned previously, the blue line needs to also have a matching "twin" angle on the other end or it is disqualified (see attched pic).

Take a look at my picture in my previous comment...all the angles obey the rules.
