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

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?
