Can you explain how it's not point?
OpenStudy (perl):
Let's define point symmetry
OpenStudy (perl):
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
OpenStudy (perl):
you can
OpenStudy (anonymous):
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
