This is more than a little dubious I know...

However given how crap I am at maths, I was wondering if anyone here could help me out? :)


I've got a triangular polygon, about which the only informaion I own are the three xy positions (points/coords/whatever) say...

(x,y)
(0,0)
(0,5)
(5,5)

Does anyone know how could I use these points work out the angles of the triangle? (To radians or degrees)

cos angle = AB.BC
|AB||BC|
