the pythagorean theorem
All the right angles
You just straighten one leg, then
straighten the other leg, clap your hands,
and you’re dancing the hypotenuse!
It’s all in the hips, really.
Sometimes, you really need to get things straight.
Ever tried to eat at a wobbly table? Annoying, isn’t it? There is an alternative to shoving
screwed-up paper under the table leg though: use the Pythagorean Theorem to make
sure your designs are dead straight and not just quite straight. Once you know this
pattern, you’ll be able to spot and create right angles that are perfect every time.
Nobody likes to pick spagetti out of their lap, and with the Pythagorean Theorem, you
don’t have to.
