label: Description
content: In this cut and folded paper model, two intersecting planes can rotateabout their line of intersection. Their motion is limited by two parallel planes that are perpendicular to the line of intersection.
label: Description
content: This model resembles one presented by George Wentworth in his discussion of a line perpendicular to two parallel planes.
