Nothing to hide. It's a great club! 
I'm an ex-math teacher also.

perhaps overkill, but pythagorean theorem would work for any dimensions, just showing off my little used math skills.
Just giving you grief.
Builders/carpenters use proportional variations all the time to check square.
3, 4, 5 or 6, 8, 10 or 12, 16, 20. Just nice even numbers you can eyeball on a tape measure without fooling with fractions.
By the way, 4 out of 3 people have trouble with fractions.

pythagorean triples oh my! now if only I had known that regular people use them so that I might have been able to convince my students to take them seriously. :yawn:3, 4, 5 or 6, 8, 10 or 12, 16, 20. Just nice even numbers ...
