Here is quite a neat way to make an equilateral triangle without using compasses:—
Take a piece of paper exactly square, which we will call A B C D, fold it across the middle, so as to form the crease E F; unfold it, and fold it again so that the corner D falls upon the crease E F at G, and the angle at G is exactly divided. Again unfold the square, and from G draw the straight lines G C and G D. Then G C D is the equilateral triangle required.
THE VALUE OF A FRENCHWOMAN
How can we be sure that the value of a Frenchwoman is just 1 franc 8 centimes?
We can be sure that the exact value of a Frenchwoman is 1 franc 8 centimes, for
| Two Frenchwomen | = | Deux Françaises. | |
| Deux Françaises | = | deux francs seize. (2 francs 16). | |
| Therefore, | One Frenchwoman | = | 1 franc 8! |

If a 52-feet ladder is set up so as just to clear a garden wall 12 feet high and 15 feet from the building, it will touch the house 48 feet from the ground.
