a rotation about the point (2, 6) result in a digram with rotational symmetry of order 2.
Coordinates of the larger shape : F'(-6,8), A(2,8), B(4,10), C(6,8), D(8,10), E(10,8), F(10,4), G(2,4), B'(0,2), C'(-2,4), D'(-4,2), E'(-6,4)
The diagram has rotational symmetry because it coincides with itself when it is rotated about the point (2,6).
