This is another square version of the Origami
Checkerboard puzzle. It uses a traditional square
Origami sheet of paper colored just on one of its sides.
You have one hundred and nine 2x2 checkered patterns
formed with small isosceles triangles; these patterns
are shown in the diagrams in this page.*
Your challenge is to achieve every of them in the minimum of single "book" folds;
see a sample. The final shape every time is a
flat square; no matter
what pattern will be at its back.
Write
us about your minimal solutions to these patterns.
All the best results will be posted.
***
Even much more difficult challenges can be finding all the
3-unit-side checkered square patterns formed with small
isosceles triangles, and their
minimal solutions. |
