What Do You Know About Flexagons? - Quiz

The term 'flexagon' is used in geometry to indicate flat models that are created when someone folds strips of paper. These flat models are often called the most fascinating geometric toys as you flex (or fold) them in a number of specific ways to reveal more faces other than the initial two.
