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?

Lace 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.
