# Origami Star

Paper folding and cutting for making a star:
This is a simulation for analyzing a paper folding and cutting activity (monkiri*) which can make shapes with 5 axes of symmetry. Please see activity 49 in Olson's book for description of this folding.
Starting with a 1X2 rectangle (a square folded in half), make a crease as shown. Adjust B' so that angle B'EF is about twice the angle AEB'. Fold F onto B', then fold A as far as possible to the right. If your estimate is good enough, you should see the angles overlap and should be one fifth of a straight angle. Drag the colored vertices to make the fold.
