Given three distinct points in the plane A (x1,y1) ,B (x2,y2), C (x3, y3)
and every point connected by a line segment, creating a triangle. How can I calculate the internal angles?
lengths AB = sqrt((x2 - x1)^2 + (y2 - y1)^2)
AC = sqrt((x3 - x1)^2 + (y3 - y1)^2)
BC = sqrt((x3 - x2)^2 + (y3 - y2)^2)
That's as far as I got.
