ActionScript 3.0 :: Project 1 Vector On The Other?

im trying to recreate the swf on that page only then in AS 3.0 I'm halfway there but i cant seem to draw the correct line on the normals of the main vector. from point0 to point1 would be vector 1, and from point0 to point2 would be vector 2. Vector2 has been drawn with the normals to its sides. (the blue cross)Vector 1 has also been drawn, its the black line thats running to the green ball.Im trying to visualize the forces of vector1 on vector2. just run the code and you'll see what i mean:

ActionScript Code:
//canvas
var canvas:Sprite = new Sprite();
var point0:Sprite = new Sprite();
var gr0:Graphics=point0.graphics;

[code]....
