Simple distances (Posted on 2006-05-01)

For this you will need four pennies. Arrange the pennies so that the centers of all four are equidistant from each other.

Example:

(1) (2) (3) (4)

This will not work because penny 1 and penny 4 are farther apart than penny 1 and penny 2.

Solution: (Hide)

Arrange three of the pennies on the table into an equilateral triangle. Then hold the fourth penny above the center of the triangle, making a 3-dimensional, equilateral pyramid.
