• 0 has two lines of symmetry (vertical and horizontal), plus 180 degree rotational symmetry.
• 1 has one horizontal line of symmetry (and 180 degree rotational symmetry) if you just write it as a line. But if you write it fancy it has no symmetry.
• 2 has no symmetry.
• 3 has one horizontal line of symmetry if you draw the top and bottom equal sized, but no rotational symmetry.
• 4 doesn’t have any symmetry unless you draw it joined up, exactly as wide as it is tall, and with no additional lines. Then it has one diagonal line of symmetry.
• 5 has no symmetry.
• 6 and 9 (which is just upside-down 6) have no symmetry.
• 7 has no symmetry.
• 8 has two lines of symmetry and 180 degree rotational symmetry if you draw the top and bottom the same size. If you make the top smaller than the bottom, it has only one vertical line of symmetry.
• 9 (see 6)

A symmetric number is a number that is the same when read backwards and forwards (i.e. left-to-right or right-to-left).
However, to be perfectly “symmetric”, a number should contain only digits that look the same, backwards and forwards.
Also note that such a number has a four fold symmetry, so it would read the same upside-down!


10 - 01 not symmetric, so 6,7,9 is also not symmetric example 9 upside down is 6
8 - 8 symmetric you can look from left, right, up, down, upside down etc.


invalid question ?
A palindromic number (also known as a numeral palindrome or a numeric palindrome) is a number that remains the same when its digits are reversed. Like 16461, for example, it is "symmetrical". The term palindromic is derived from palindrome, which refers to a word (such as rotor or racecar) whose spelling is unchanged when its letters are reversed. The first 30 palindromic numbers (in decimal) are:
0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 11, 22, 33, 44, 55, 66, 77, 88, 99, 101, 111, 121, 131, 141, 151, 161, 171, 181, 191, 202
then your question should have been which number is not palindrome, because 10 u read as ten and 01 you read as zero one, symmetric number is number like 8, you can't change it, rotate it, look from different angles, it will always be 8

polindromic numbers are also symmetric ....

Quoted from "FantazikZenci"

They are not symmetric. the word polindromic means can be read front or backwards and will result the same does not mean symmetric.... how is 9 symetric? there is no symmetry as reading backwards or forwards resulting the same symmetry.

i mean value's not changing for 6,7,8 and 9... but for 10 value will be 01 = 1
and pls stop...
