The letter H has linear symmetry, but it has another kind of symmetry as well. Notice the yellow star on the H below. It is in the top left corner of the H. Push the button below the H and see where the star ends up.
The yellow star ended up on the bottom right of the H after it rotated. Even though it was in a different place, the H still looked the same. When a figure looks the same after it is rotated we say that it has rotational symmetry. The key though is that the letter cannot rotate a full turn. It must be less than a full turn.
The letter W does not have rotational symmetry because it does not look the same after it has rotated.
Does the letter N have rotational symmetry? Make an educated guess and then push the button to find out.
