In mathematical terms symmetry can depend on the binary operation defined on a set.
1.... No.politics 2.
1 and 8 are symmetrical both horizontally and vertically and 3 is symmetrical horizontally.
Look: 0 1 2 3 4 5 6 7 8 9 0 is doubly symmetrical (horizontal and vertical axes) 3 is almost symmetrical about the horizontal axis 8 is almost doubly symmetrical 1 is almost symmetrical, and is truly symmetrical in some sans-serif fonts (but not in all languages: cursive French has a long leading stoke on the left)
Only if it's drawn as a straight line. If the horizontal line at the base, and the sloping line at the top are added, it is not symmetrical.
ask a teacher!
if AD-BC=1
Yes it has 1 line of symmetry

Symmetrical primes are prime numbers that remain the same when their digits are reversed. The symmetrical primes between 1 and 100 are 2, 3, 5, 7, 11, 101. These numbers are prime because they are only divisible by 1 and themselves, and they are symmetrical because they read the same forwards and backwards.
Such shapes are known as symmetrical.

0 is symmetrical because when something is symmetrical it can be split down the middle and have two symmetrical sides or two sides that look the same. If you draw your ones like a straight line then it could be symmetrical depending on your teacher. If your teacher allows you to make your symmetrical lines going horizontal instead of vertical then 3 would also be symmetrical. F.Y.I if you don't trust a enrichment middle schooler who has learned this recently then don't use this information
