If point1 and point2 are defined by (x1,y1), (x2,y2), you can get the angle by
atan(abs(y2-y1)/abs(x2-x1)) % radians
% or
atand(abs(y2-y1)/abs(x2-x1)) % degrees
If you want to programmatically define the two points as well you'll have quite a bit more work to do starting with a solid definition of how they are located.
