An Infinite Ruler A) Postulate 2 ‘The Ruler Postulate’ a. The points of a line can be placed in correspondence with the real numbers in such a way that…… 1. to every point of the line there corresponds exactly one real number 2. to every real number there corresponds exactly one point of the line 3. the distance between any two points is the absolute value of the difference of the corresponding numbers b. Coordinate system i. The number corresponding to a given point is called the coordinate of the point c. Ex) A B C
