This model is a 3-Dimensional Flexagon made from triangles. You can rotate this model to make many interesting patterns. To make this model you need a card sheet. Mark eight strips. The strips have lengths of 6, 5 and 3.5-cm. All strips are 2.5-cm wide. Cut all 8 strips. Then with the help of a scale fold each strip on two marked blue lines. Fold each strip into a right angle triangle and tape the ends. Tape all 8 strips to make right angle triangles. Bring two triangles as shown and tape their hypotenuses together. Make 4 such pairs of two triangles each. Bring the two blue lines of the pairs together and tape them. This will join 4 triangles. Make another formation like this. Bring both these set of 4 triangles together. Here you can see four facets marked with a “X”. Tape the joints of the “X” marked facets. This will join all 8 triangles and will complete the model. Now you can flex or rotate your model to make a Diamond or an Oval Shape. You can make a large square or a flower with 8 petals. You can spend a lot of time flexing the model and discovering many interesting patterns.
