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 )
O and X And H and I (Note "O" has many, actually an infinite number of, lines of symmetry)
I x o l
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."
Z S H and N
H, I, and O
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.
