9
the line which divides the number into 2 equal halves is called symmetry in numbers example:- in digits 0 to 9 the symmetry of numbers are 0, 1, 3, 8.
Triangle * * * * * The only triangle with rotational symmetry of order 3 is an equilateral triangle and that has 3 lines of symmetry, not 0. The triskelion (the three legs) on the Isle of Man flag has rotational symmetry of order 3 but no lines of symmetry.
yes, a circle.
A triangle can have 0, 1 or 3 lines of symmetry.
triangles have 0 rotational symmetry
0,one full turn doesn't count as a rotational symmetry

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.
0, 8, and possibly 1 depending on how you write it. Anything with only these numbers in a palindromic form (18081) is symmetrical too.
Yes. It has two lines of symmetry - horizontal and vertical. It also has 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.
yes, a circle.
no, only single digit numbers are 8,3,1, and 0
A hexagon can have rotational symmetry of order 1, 2, 3 or 6.It can have 0, 1, 2 or 6 axes of symmetry.
