Summary
| Description | Folding a rectangular sheet of paper into thirds using the crossed ladders problem by CMG Lee. The optic equation of the crossed ladders problem can be applied to folding rectangular paper into three equal parts. One side (the left one here) is partially folded in halves and pinched to leave a mark. The intersection of a line from this mark to an opposite corner with a diagonal is exactly one third from the bottom edge. The top edge can then be folded down to meet the intersection. |
