Tonight’s talk: Integer solutions vs non-integer
solutions for right triangles
Integer solutions:
I guess we’re quite a famous family. Most people can
recognize at least one or two of us. 3-4-5 gets the
most attention but that’s not the whole range.
Yeah but you totally need a calculator—nobody
knows the square roots of weird numbers by heart…
and who carries one of those around? We integer
solutions are convenient—especially if you can
remember them!
Us—precious? You’re the one with all those high-
maintenance decimal points, baby.…
That’s true. I always think you look better that way
actually.…
Non-integer solutions:
Range schmange. We don’t have a range—think of
a number, and we can find you a solution. We non-
integer solutions are flexible. Any size, any place,
you can still have a right angle.
Remember? People forget we even exist—never
mind learning specific versions of us…you lot are so
precious.
Oh, I knew you’d bring that up. Yeah, yeah, we’re
detailed—OK? But cell phones and computers have
