    Can you explain how it's not point?

    Let's define point symmetry

    point symmetry is symmetry about a point, I believe it is also called rotational symmetry. Can you rotate H so that it coincides with itself , by an angle less than 360 degrees. ?

    No. You can't. Therefore it's only line

    Dang it. How can you? Is it by dragging the ends to another end?

    cut out the letter H with a piece of paper, and rotate it by hand. using the center as the point of symmetry

    Oh....Okay. Thank you. And it's not plane is it?

    Plane symmetry is used for objects that are 3 dimensional. since this is a 2d figure i don't think it applies.
