Relation to other fields of mathematics
Origami relates in many ways to different fields of mathematics. For example, many teachers in high schools use origami to teach many topics in their curriculum. Areas included are problem solving, geometry, ratios, angles. logic, proofs, congruence, properties of parallel lines, and the list goes on. (Serenevy, 2003). One example Robert Lang gave in his TED talk was the fact that any origami figure can be unfolded and colored using only 2 colors. This would be a good example to show in a discrete mathematics class in high school (INSERT CITATION). There is also a fairly obvious connection to the field of geometry. Many geometric shapes and designs can be made with one sheet of square paper using different folds. Overall, even though the mathematics is starting to have a much deeper role in the creation of origami figures, there is a practical use for this math at a high school level relating to several different mathematical fields.
