8 has vertical symmetry.
No
yes it is
No you cannot have an irregular octagon with three symmetrical lines and just to let you know that 5 billion - 2 = 4,999,998 and you can do an endless sum with all four number operations - + % x and 5 kerzillibillion - 10 kerzillibillion = -5,000,000,000,000,000,000,000,000.
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.

It is symmetrical
In many fonts, all four are symmetrical (about a horizontal axis).
In mathematics, symmetry refers to a property where an object remains unchanged when it undergoes a transformation. For a number to be symmetrical, it must read the same forwards and backwards. For example, the number 121 is symmetrical because it reads the same forwards and backwards. However, the number 123 is not symmetrical as it reads differently when reversed.
