Paper Folding Test
The two figures on the left represent a square piece of paper being folded. In the second figure a small circle shows where a hole has been punched through all of the thicknesses of paper. Choose the drawing on the right that shows where the holes are after the paper has been unfolded.
Show how the present geometry could have been derived by folding and faulting.
