perpendicular bisector of (-3,-7) and (1,-7) is x=-1
perpendicular bisector of (-3,-7) and (-3,3) is y=1/2
so the both intersects at (-1, 1/2)
hence 2.(-1, 1/2)

The rotational symmetry of a shape explains that when an object is rotated on its own axis, the shape of the object looks the same.
Hope it will be helpful :)
