The states of Colorado, Utah, Arizona, and New Mexico all meet at a common point, popularly referred to as Four Corners. This point is analogous to the origin (i.e., 0) on a two-dimensional X-Y Cartesian plane. (You may recall from elementary algebra that the Cartesian plane is separated, by way of the X and Y axes, into four separate regions that meet at the origin.) so... Question 1: Do the States of Colorado and Arizona touch each other ? Question 2: Do the States of Utah and New Mexico touch each other ? Question 3: If you answered yes to Questions 1 & 2, please explain how this is possible.
