Hello ADIYTA
IXX, IYY and IZZ are indeed the mass moment of inertia. In a 2D object you can use the perpendicular theorem to calculate the 3 of values of IXX IYY and IZZ. IZ=IX + IY , if the object has rotational symmetry then you have the advantage of having IX = IY (XY is the plane of your rotating object)
