no sooner did i hit send when i recalled what to do. i got it now, ta anyhow. j.

but for those who want to file away how to do the math.....

you would square the two sides (12 x 12) + (12 x 12) which would equal 144 +

Then you need the square root of 288 which is 16.9705

Calculating triangle sizes --- maybe one of these will help:

It's not that complicated. Simply multiply the length of the side (12" in this case) by the square root of 2 (1.414). Result is 16.97. Let me know if you need the algebraic proof. :)

a square + b square = c square.... Who knew that darn algebra would come in so handy one day in real life. Please share this with your teenagers... ~:o)

I don't think I can still do that (it's been too long >gand I don't know why -- but I even remember how to calculate the square

That's what the square root key on a calculator is for, isn't it? :) (Though I still have my slide rule and could do it on that, too -- if I can remember where it is!)

Oh, a girl after my own heart! I still have my first slide rule!
