Quick Summary

A flexagon is a paper figure that can be flexed along its folds to reveal different arrangements of its faces.

Through specific folding and gluing, this model can change its visible face when flexed. Flexagons have been a mathematical recreation since their discussion began in 1939.12

Flexagons
…the simplest flexagons is the trihexaflexagon, made by cutting a strip of suitable material and marking off 10 equilateral triangles. By folding appropriately several times and then gluing the last triangle onto the reverse side of the first triangle, the resulting model may be flexed so that one of the…
