Positioning elements inside Triangle

I want to develop a Christmas tree, how can i populate this triangle with elements dinammicaly loaded from the library?..the code so far…
<code>
for(var i:Number =0; i<MenuArr.childNodes.length ;i++){
var star:MovieClip = _root.attachMovie(“estrella”,“star”+i,_root.getNextHighestDepth());
star.starId = MenuArr.childNodes*.attributes.id;
star.nombre = MenuArr.childNodes*.attributes.nombre;
star.texto = MenuArr.childNodes*.attributes.texto;
//Posicionamiento.
star._x = randRange(coordenadas[3], coordenadas[2]);
star._y = randRange(coordenadas[1], coordenadas[0]);
if(landing_mc.hitTest(star)){
//star._alpha = 20;
};
};

function boundsLanding():Void{
var bounds_obj:Object = landing_mc.getBounds(this);
for (var i in bounds_obj) {
coordenadas.push(bounds_obj*);
};
};

//Random a partir de un RANGO.
function randRange(min:Number, max:Number):Number {
//trace(min); trace(max);
var randomNum:Number = Math.floor(Math.random() * (max - min + 1)) + min;
return randomNum;
};
</code>

txs in advance!
