Can you fold a 8.5 in x 11 in (US Standard) piece of notebook or typing paper in half and draw a single 13 inch straight line on ONE of the four faces of the folded paper?

### Hint

Think of different ways you can fold the piece of paper so it is ALWAYS folded in half.An unfolded sheet has two sides (faces); front and back. A sheet folded in half has four faces (sides); two each on what was the *front* and two each on what was the *back*.

### Answer

Fold the paper corner to corner so the crease is diagonal. Don't fold it horizontally or vertically. The four faces, or sides, would then be triangular and not rectangular (as other folds might be). But the paper IS folded in half. Then, along the longest edge of one of the four faces, draw your single 13 in. straight line.Hide Hint Show Hint Hide Answer Show Answer
