the same upside-down? You might like to try this investigation and

Sapna who goes to Sacred Heart School, looked
at what happens to the letters of the alphabet when they are turned
through a half turn, followed by a sideways flip. She drew out the
letters one at a time and here are the ones that stay the same:
Of course, it will depend
slightly on how you write the letters, but well done Sapna! Sam
from Bispham Drive Junior School agreed with this list and
These letters all worked because they have a horizontal
line of symmetry. When doing a half turn they are upside down and
backwards and flipping them over makes them right.
Can anyone answer the rest of the question? Do
these letters stay the same with a half turn followed by a flip
from top to bottom?
