Now that we know how to fold a rabbit ear, I would suggest analyzing a few traditional origami bases to see if we could find rabbit ear there.įirst, the obvious starting point is a so-called fish base. They all coincide with one another, which is what we wanted in the first place. Figure 1Īs you can see in figure 1 upon folding, all triangle’s sides are aligned. In other words, we have to add a mountain fold that is perpendicular to the paper side (Figure 1B). A solution to this problem is obvious and very simple we have to add one additional crease at that node. Additionally, the number of folds at that node is an add number which is not allowed. All three creases that converge in that node are valleys. But from a flat foldability standpoint, this point (or node) does not satisfy one of the basic origami rules, namely the Meakawa-Justin theorem. These three bisectors will intersect in a single point which is more than convenient. To do so, first, we have to define or fold angle bisectors of all three triangle’s corners (Figure 1B). We will make its sides to coincide we will make them all appear on the same mutual axis. And since by definition, a rabbit ear is a way to force triangle sides to coincide, we will do exactly that with one of these triangles. So, to show you a procedure, let’s take a square piece of paper and let’s fold it along the diagonal (figure 1A). Folding procedureīefore we start to talk about the importance of rabbit ear, it would be wise to know how to fold one. In its essence, a rabbit ear is an elegant way to force three lines or folds that forms a triangle to coincide. Origami rabbit ear is one of the primary folds in origami. Post is a part of a larger series (Uniaxial base):
