Antiprisms

After making origami prisms in the previous post, it seemed natural to try out the antiprisms next. Antiprisms are similar to prisms but the difference is that the side faces are triangles instead of parallelograms. Also, the top and bottom parts are twisted, relative to each other.

For these antiprisms, I used 3.5 inch squares - 3 squares for the triangular antiprism, 4 for the quadrilateral one, 5 for the pentagonal antiprism and 6 for the last one. The model isn't very stable though, and requires a dab of glue to hold it well in place.

A variation to the prisms gives a slightly different shape, when the sides are creased in. This gives a multi-sided star shape - like the 3-sided star and the pentagonal star in the pic.

This modular origami is again from Miyuki Kawamura's book - ‘Polyhedron Origami'.
