The square in the right angle symbol...

What is the name / is there a name for the square in the right angle symbol?  My geometry teacher did not know and would give extra credit to anyone who finds out.  I have been looking everywhere for its name but its never said.  If you know, please tell me what it is!

Thank you,
Jack

Re: The square in the right angle symbol...

the square is there to show that the catets are perpendicular...since we know that all the edges in a square are perpendicular.

Re: The square in the right angle symbol...

I have searched through some dictionaries, and not found any name for the right angle symbol. Perhaps its name is "right angle symbol" smile

And kyle, I am fascinated by the name "catets" - it does not occur in English, but some spanish (and portuguese?) websites seem to indicate it means the two sides that are not the hypotenuse - is that right?
