I have some question guys(adsbygoogle = window.adsbygoogle || []).push({});

i have four points in the x,y plane in cartesian coordinates.

A (Ax,Ay)

B(Bx,By)

C(Cx,Cy)

D(Dx,Dy)

A and B is vector G

C and D is vector F

I would like to know what is the equation to get the angle between those two vectors (G,F) . and what are the limitations of this equation.

thank you
