What is digon?

A digon is like a shape made by connecting two lines and closing them, just like when you fold a piece of paper in half and tape the ends together.

Imagine you have a strip of paper, like the one you use to wrap a gift. If you take that strip, bring the two ends together, and tape them so they form a loop, what do you get? You’ve made a digon! It looks almost like a very skinny circle, but instead of having many sides, it only has two.

Think about your favorite necklace. If it had just two beads and the string was tied between them to make a loop, that would look like a digon too. The necklace isn’t round, but it’s still a closed shape, just with two sides instead of many.

Even though you can’t really see a digon clearly on paper because it's so thin, in math and geometry, it helps explain how shapes behave when they have very few sides. It’s like the simplest kind of loop you can imagine!
