Oh, what a lovely question! When a letter has diagonal symmetry, it means you can draw a line from one corner to the opposite corner, and both sides will be mirror images. The letters with diagonal symmetry are "A," "H," "I," "M," "O," "T," "U," "V," "W," "X," and "Y." Just imagine those letters smiling back at you with perfect balance and harmony.
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)
Seven
None. Some letters have one or more but all the letters, taken as a set, have none.
