- _delirium 14y agoTangentially related: although you're probably suggesting trisecting an edge with origami folds (which is straightforward), the mention of dividing by three using physical methods reminded me of the classic trisecting-an-angle problem, which apparently is also solvable with origami folds [1], even though it isn't solvable with compass and straightedge [2].

- dedward 14y agoYup - they're the same thing... you trisect the angle from the corner, and end up with an edge neatly in thirds. Surprised me when I found it too - neat stuff, paper.
