O and X And H and I (Note "O" has many, actually an infinite number of, lines of symmetry)
Five.H , I , O , X( ' O ' has 2 lines of symmetry and more besides and ' X ' has 4 )
four
2 lines of symmetry
If you are talking about a perfect circle, it has wan infinite number if lines of symmetry. If you are talking about and actual lower case o, then the answer is two.
none
An infinite number
Lower case "o" and "x" both have two lines of symmetry. Upper case letters with two lines of symmetry are: "O," "X," "H" and "I."
The letter 'O' has unlimited lines of symmetry .
It not just has a line of symmetry; a perfect circle has an infinite number of lines of symmetry.
Vertical lines of symmetry: A, H, I, M, O, T, U, V, W, X, Y Horizontal lines of symmetry: B, C, D, E, H, I, K, O, X Other: O
