document.write( "Question 1194898: Can you explain why a three-legged stool is often more steady than a four-legged one? If you have a four-legged one, is it possible that all four legs might touch the floor at the same time? Is this true for a three-legged tool? Relate this to geometric situations involving three points and a plane and four points and a plane.

Three points define a plane. A fourth point now has four different groups of 3 points and therefore four different planes (4C3).
