Pythagorean Theorem and Coordinate Plane

Did you lose the co-ordinate plane???

That is terribly sad, and it will be a great loss to all of us here.    

I don't think Pythagoras would have it,  not even in theory.

Try looking under the bed., or it may be with an odd sock between the sheets at the end of the bed.

That is where I usually find things.  

OR maybe it is under the cushions of the lounge, it is amazing what can be found there !!!
