I'm not really sure if these are correct. I hope they are and I hope they help you out.

Answer 2

Answer:

1a 2a 3b

Step-by-step explanation:

1) a

This 6 point star has 6 lines of symmetry. That's what has been called Rotational Symmetry.

And yes it does have point symmetry because from the center to its points there is an equidistance. Check it below.

2) a 2; no.

For a moment the cross inside leads our vision away to the fact that this is a rectangular form.

So the answer is "b": two lines of symmetry and no point of symmetry Because there is no equidistance from the Center point to the matching parts.

3)  b. 2; no

A rectangle has two lines of symmetry and no point symmetry.  For the reasons explained above.
