In caps there is 1. lower case none.
Assuming thatdiangle = diagonalsemetry = symmetryoctigon = octagonthe answer is 0, 1, 2, 4 or 8.
zero, all the keys have different letters, numbers, or symbols
the answer is U O S H K Z X N A D=2 0R MORE LINES OF SYMMETRY
2 lines OF SYMMETRY
There are infinite lines of symmetry, as in the case of a circle, the diagonal is the line of symmetry. The diagonal can start at an infinite number of places, and thus there are endless possible lines of symmetry.
Six - three from diagonal to diagonal, three from midpoint of a side to midpoint to a side.
How many diagonal lines does a 1million sided shape have
7
It has no reflection symmetry because the white diagonal lines are thicker on one side than the other.
'2' . From opposite corners.
A parallelogram need have no lines of symmetry.
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 )
4 (1 horizontal: left to right, 1 vertical: up and down and 2 diagonal)
H,I,O,X Note that if you draw "O" as a perfect circle, it will have infinitely many lines of symmetry.
Seven
