How could I retrieve angle between two edges...?

[Masoud]

Hi;

In VEX, how could I retrieve angle between two edges that are connected to a specified point?

I tried these codes, but it shows 180 degrees instead of 135 ..!

int SelectedPoint = 1;
int SrcPoint = 0;
int DestPoint = 2;

vector pBasePos = point(0, "P", SelectedPoint);
vector pApos = point(0, "P", SrcPoint);
vector pBpos = point(0, "P", DestPoint);

vector VectorA = pBasePos - pApos ; 
vector VectorB = pBasePos - pBpos;

f@angle = degrees(acos(dot(VectorA,VectorB)));

Thanks.

normalize your vectors before doing dot()
