I have a simple question, and I've looked over the internet and can't find a numerical way of doing it.
I only found how to do this using a ruler and a compass, which I can't use, since I'm doing a computer program.
I need to calculate the bisection angle for line segments ABC. I need to calculate the inner bisection angle and the outer bisection angle.
EDIT: dividing the angle by two won't work.
Let me explain it a bit better: this linestring, which contains the vertices A, B and C is used to generate a polygonal buffer. I use the linestring to find out the angle (medium angle between AB and BC) that will be used to construct a line, used to split the polygon mentioned earlier.
