RIDDLE: How can you arrange four ordinary wineglasses on an ordinary table so that "foot" (center of the bottom of the stem) of each is the same distance from all the others?
ANSWER: Place the first three in an equilateral triangle so that the foot of each is the same distance from the others as the height of a wineglass. Then place the fourth wineglass in the middle of the triangle, upside down.

Not quite.
This isn't right. The foot of the fourth wineglass will be a greater distance from the feet of the other wineglasses than the height of a wineglass, and so that distance will not be the same as the distances between the feet of the first three glasses. However, the construction can be made to work, if the feet of the first three glasses are moved a little over 22% further apart.
