## How is Origami Math?

Will be elaborated, and spell-checked/revised soon. I just wrote what my heart told me to, and my heart isn't grammatically correct most of the time :) I am posting this unfinished so my readers can have some content.

| ## How can Origami be Math?## IntroductionHave you ever folded a crane? If not, you can follow the instructions on This link. Your first crane probably won't be pretty ,if you even manage to fold it. You start by folding the paper in half. You are dividing by two. To make the base, you make eight isosceles right triangles. When you make the wings, you are constructing a right triangle with predetermined legs. Every step of almost every origami piece can be described like this. Because of this, its not surprising that when you unfold the crane the crease patterns on the paper make angles that are 60º, 90º, 45º, 30º, and other angles with mathematical signifigance. It isn't shocking that a lot of the figures formed by the crease lines are congruent and often regular polygons. Every fold in the crane makes some mathematical figure. But did the original creator of the crane try to do that? No. He didn't lose any sleep over whether he made common angles in the creases. So why are the creases so mathematically "perfect"? Like everything in the universe, origami abides to general rules. You will very seldom come across an origami project which says "Vally fold a random section of the paper to the other side". You instead fold to an existing crease or edge. If you are always folding to an existing crease, you are just making a geometric construction. ## Okay, it might be math. Who cares, and how is this |
