the part for rotational symmetry that is 4)a)i)a is order 3 try using the centre of the shape as the invariant point and rotate it, (one trick of doing it think about it as a stencil u have of this shape and u take the shape out and rotate it and fix it u will see u can do it 3 times !
by what angle should i rotate it
