Could someone please help me with this proof?
I have to come up with a proof to show that a word, written in capital letters, is unchanged when reflected in a horizontal line and a vertical line. That just means that it needs to be able to be reflected across the x and y-axis, right?
So, I need to find a word that just has I's O's and H's in it, right?
Can anyone show me how to do a proof like this?
Thank you very much
