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
#10
- It has rotational and point symmetry but not line.
#11
#12
- It has rotational and point symmetry.
