Trigonometry with pic.rotate help

[david92ng]

we have one point (x,y) and we have an other point(x2,y2)

x,y is the center.
lets say x2 and y2 is some random point around the center.

now the question, i want to draw a picture at the center(x,y) and after i will use pic.rotate it so it will point to x2,y2.
To do that i somehow need the angle from the center to the other point.

i totally forgot Trigonometry which i know i need to use for this. can someone give me the formula?
thanks

Turing:

fcn getAngle(x1, y1, x2, y2 : real) : real     /*Some code shamelessly stolen from Bored*/     var opp := y2 - y1     var adj := x2 - x1     if adj = 0 then         if y2 > y1 then             result 90         else             result 270         end if     elsif opp >= 0 and adj > 0 then         result arctand (opp / adj)     elsif adj < 0 then         result 180 + arctand (opp / adj)     elsif opp < 0 and adj > 0 then         result 360 + arctand (opp / adj)     end if end getAngle

Just pass in the coordinates of your two points.
