Recall properties of symmetry:

  • Line - reflection mirror,
  • Rotational - you can rotate it about its center and it will overlap with the initial shape after minimum of 180 degrees rotation,
  • Point - acting as a midpoint of the segment formed by opposite points.

Using the properties we can state that:

#9

  • It has no symmetry.

#10

  • It has rotational and point symmetry but not line.

#11

  • It has a line symmetry.

#12

  • It has rotational and point symmetry.
