It does have 16 lines of reflectional symmetry, since it reflects the other half of the shape, not a shape but i feel like you know what I mean.
It also does have a reflectional symmetry as shown above of how many ^
It also has rotational symmetry with an angle of rotation of 90 degrees since you can rotate it 90 degrees and still have the same shape.
But other than that I'm hoping this helps out dude if you have any more questions go ahead and ask my dude ^^
