Hint
5.
Tell whether the recycling symbol shown at the right has rotational symmetry. Explain.
A.
No; it will only fit exactly over itself after being rotated 360°.
B.
No; it does not have line symmetry so it cannot have rotational symmetry.
C.
No; it has line symmetry but not rotational symmetry.
D.
Yes; it fits exactly over itself after being rotated 180° or less.
