Heptagon — Arnold Tubis

Folding/One-Cutting a Regular Heptagon

Here is a simply landmarked method of folding/one-cutting a regular heptagon that is very accurate, and for most practical purposes in origami, may be considered to be exact. Applying one of the folding methods that is mathematically exact when applied to idealized (infinitely thin and flexible) paper (that does not exist in our real world) would, in practice, yield a less accurate result.
