Well, honey, numbers like 11, 88, 69, and 96 have rotational symmetry because they look the same when flipped or rotated. Just like a good martini, these numbers are perfectly balanced no matter which way you turn them. So, if you're looking for a numerical twirl, those are the ones to go for between 100 and 1000.
Numbers that have rotational symmetry are those that look the same after being rotated by certain angles. In the case of single-digit numbers, the numbers 0, 1, and 8 have rotational symmetry. When rotated 180 degrees, 0 and 8 look the same, and when rotated 90 degrees, 1 looks the same. Numbers like 2, 5, and 6 do not have rotational symmetry as they look different when rotated.
Only 8 although in some fonts, also 1, 2 and 5.
0, 8, and possibly 1 depending on how you write it. Anything with only these numbers in a palindromic form (18081) is symmetrical too.
There is no difference because watch this ... 3 0
The number 3.

No, because the numbers are not symmetrical.

I have revised this answer. This question is harder than it looks!The numbers 69, 6009 or 98886, for example, would have rotational symmetry (looks the same when rotated by 180 degrees) but not reflection symmetry.So I think the answer is going to be something like:A number which consists of the digits 6 and 9 plus or minus the digits 0 & 8 AND has the digits in the necessary order to maintain rotational symmetry.

It depends on how you write them. For example, 2 written here has no symmetry. Where 2 on an LCD display (eg on an elevator/lift would have rotational symmetry) Usually 0 and 8 have both horizontal and vertical symmetry.

In some fonts, the numbers have rotational symmetry of order 2.
It can have 0, it can have 8, and some numbers in between.
0, 1, and 8 have symmetry. (:
