Given a strip of paper with congruent parallelograms of base and smaller angle being bisected, one can construct a regular -gon using the fold and twist (FAT) algorithm.


With "pentagon" unchecked, you see just the first step of the algorithm for . With "pentagon" checked, you can go through the complete algorithm for constructing a pentagon.
