 #Isolate one triangle.
 #Ask the child to identify each of the angles, and the biggest and smallest angles.
 #This angle which is neither smallest nor biggest we can call the medium angle.
 #The child names each angle: smallest angle, medium angle, biggest angle.
 #First star: Let's unite all the triangles by their smallest angle.
 #The directress positions a few and allows the child to continue.
 #How many points does this star have? Twelve.
 #With all of the triangles at our disposal, we can make only one star with twelve points.
 #Second star: Let's unite all the triangles by the medium angles.
 #How many points does this star have? Six.
 #Try to make another star with the triangles that are left.
 #With all the triangles at our disposal, we can make two stars with six points.
 #Third star: Let's unite all of the triangles by the largest angle.
 #How many points does this star have? Four.
 #This symbol is very famous; it is the star of Saint Brigid, the patron saint of Ireland.
 #Try to make another star like this.
 #With all the triangles at our disposal, we can make three stars with four points.<br>
