Puzzles and Curious Problems by Henry Ernest Dudeney: $201$
- Square and Triangle
- Take a perfectly square piece of paper,
- and fold it as to form the largest possible equilateral triangle.
- A triangle in which the sides are the same length as those of the square, as shown in our diagram,
- will not be the largest possible.
- Of course, no markings or measurements may be made except by the creases themselves.
