Origami #6: Pentagonal Pyramid

Origami #5: Pentagons

This week: fun with geometry. I found a very interesting book called "Amazing Origami" by Kunihiko Kasahara. It has some very interesting projects in it, but it really focuses on the geometry behind origami. This project uses a few simple folds to create first a doubled pentagonal pyramid shaped something like an hourglass (see side view photo),

then shows how the whole thing can be taken apart, cut in half, and reconstructed into two individual pentagonal pyramids.

Okay, not a very exciting project for the viewer, but the geometry is kind of interesting and the explanations of how this all works are simple enough to understand even for someone who struggled with basic geometry in high school.

Tomorrow, something a bit more visually exciting from the same book.
