the answer is U O S H K Z X N A D=2 0R MORE LINES OF SYMMETRY
Five.H , I , O , X( ' O ' has 2 lines of symmetry and more besides and ' X ' has 4 )
I x o l
O and X And H and I (Note "O" has many, actually an infinite number of, lines of symmetry)
The letter L has no lines of symmetry, you cannot divide it in to 2 identical halves.
2 lines of symmetry
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."
H, I, and O
Z S H and N
H,I,O,X Note that if you draw "O" as a perfect circle, it will have infinitely many lines of symmetry.
Three capital letters that have two lines of symmetry are "O", "H", and "I" since they can be reflected either horizontally or vertically and still look the same.
