Subject: What to do when squares go bad?

And while I got your attention, how would one check if a 45 degree angle
from a combination square is correct? My high school geometry is getting
fuzzy nowadays. I gotta get those 45 degree shooting rails right too!

Plane a right-angle and try the correspondence trick by scribing a line
drawn from each edge.

Mind you, you have to have a decent square to get a 'right' right-angle in
the first place.

Reminds me of a song ............ There's a hole in my bucket, dear Liza,
dear Liza ....................

And it's perfectly respectable too, though list-mommy might object!
