Naoimi says all of the numbers she wrote have line symatry. is she correct

No because let's say she wrote 1, the number, it is not correct because some figures don't have equal lines of symmetry :)

No, she is incorrect

Explanation:

Lines of symmetry are always equal. The number 13 is not a line of symmetry because the number does not have equal line of symmetry.

Meaning of Symmetry: Symmetric figures are figures that can be folded to make two halves that match each other. The lines that divide a symmetric figure into matching parts are called lines of symmetry.

Hope this helps!
