Fastest way to connect 4 points with non-intersecting lines?

Question

Trigonometry

Hello.
I work with OpenCV, I need to quickly connect 4 points (in X and Y coordinates) with non-intersecting lines.
Can you please tell me what is the fastest way?

Answer 1

what nonsense, all lines will intersect, at points.
no matter how you draw lines on 4 points, you will get 2 triangles with one common edge, so feel free to connect in the 'all points to all' cycle, without repetitions.
