**Make An Origami And Show That Maekawas Theorem Is True**. He is a member of the japan origami academic society (jaos) and japan origami association. Cut a notch on both sides of the middle of the shorter strip and tie with string.

’f’, ’b’ range over the real numbers. Maekawa's theorem is a theorem in the mathematics of paper folding named after jun maekawa. Figure 1(a) shows an example of a vertex that will not rigidly fold, namely a degree.

### It Looks Like A Mountain.

This is essentially maekawa’s theorem. Maekawa’s theorem, which requires the number of mountain folds minus the number of valley folds at every vertex to be t2 for a structure to fold flat (24). This shows that both maekawa's theorem.

The difference between the number of mountain and valley creases in a ﬂat vertex fold is always two. This image shows an unfolded paper crane. This should leave about a 1 unfolded section at the top.

• the vertex is in the paper’s interior (not on the boundary of the paper). So that proves the theorem. Also, a hinge crease is a line around which a flap can rotate.

### And That's Why, In A Degree 4 Vertex, One Of Them Has To Be 3, The Other One Has To Be 1.

By definition, a hinge crease is a line that defines polygons by the mere fact it surrounds it. However, in fact, we will prove that the theorem is even true for all complex numbers (with the exception of a=0). Deriving maekawa’s theorem can be done using induction and graph coloring, by considering the graph representation of a crease pattern.
