the arrow heads are part of the shape 
2 i think,

parthkohli · Answer

It does not have any rotational symmetry, as we can't see the same figure throughout the rotation.

unklerhaukus · Answer

what if we flip it upside down?

parthkohli · Answer

Then the arrows would be facing the other side.

parthkohli · Answer

This is plane symmetry, not rotational symmetry.

unklerhaukus · Answer

but rotating around the dotted line

parthkohli · Answer

The centre of rotation is the middle intersection..

unklerhaukus · Answer

you are probably right PathKohli
