Problem number 18. Rebecca folds a square piece of paper twice. Then she cuts off one corner. Next she unfolds the paper. What does the paper look like once unfolded?  Here's the diagram showing which way she folded the paper. First she folded it up, then she folded it over to the right side, and then she cut off the corner here.  Let's continue the steps of actually showing where the corner is cut off and then unfolding the paper. Here's a close-up. When she cuts off the corner, it looks like this.  The paper was folded over to the right, so the unfolded piece will come on the left. And then the paper had been folded up, so when it's unfolded, it will be on the bottom.  So we see the part that was cut off right here, and this is answer B.
