Assuming "rotational symmetry" means looks identical when rotated 180 degrees. H I N O S X Z
H, I, N, O, S, X, Z
They are H, I, N, O, S, X and Z.
There are seven: B, H, I, O, S, X, Z
SYMMETRY
H, I, O, and X have rotational symmetry.
7 have rot
What is the angle of rotation of alphabet S
Assuming "rotational symmetry" means looks identical when rotated 180 degrees. H I N O S X Z
H i n o s x z
H, I, N, O, S, X, Z
They are H, I, N, O, S, X and Z.
No. The only uppercase letters with rotational symmetry are H I N O S X Z Lowercase are l o s x z (and t depending on how it's drawn)
A B C D E H K M U V W X Y * * * * * What? Most of these letters do not have rotational symmetry and so cannot have rotational AND line symmetry. Or did the meaning of AND change last night? The only upper case letters with both are H, I, O, X
There are seven: B, H, I, O, S, X, Z
SYMMETRY
A trapezium does not have rotational symmetry.
