Full NameComment goes here.needmath'Through every pair of different points there corresponds to a positive real number'The theorem you state refers to distance between the two points, or length of the segment having the two points as endpoints. All distance will be positive and real (not just positive integers or whole numbers, they can be rational or irrational). You can explain using a number line. You can have students demonstrate by uisng strips of paper to represent the distance between two points. Have students measure, then cut strip, measure the pieces, cut, measure the pieces, so on. This demonstrates that 'any' of the pairs of points will have a positive real number length. Obviously, this demonstration uses inductive rather than deductive reasoning.
