Origami

Today, I saw Origami. I have heard that means folding a paper to make something. However as long as I was watching about Origami, I didn't understand almost heard. But I could know a little what was going on to show on TV. The surprising was there was mathematics's records. To unford a folding paper, one standard strait line has left side and right side. The left side seemed same as right side. It was surprised.
