State the ruler postulate.

Answer:
Ruler Postulate Summary. On a number line, every point can be paired with a number and every number can be paired with a point. The number associated with a point A on a number line is called its coordinate. The distance between two point A and B is denoted by AB
Answer:
Step-by-step explanation:
The ruler postulate determines how the distance between two points can be found. First, we must match a number to each of the two points. We call the coordinates of the points these numbers. Then we subtract each other's coordinates. If the resulting difference is negative, we take the result's absolute value as the distance is always a positive number. The formula for same is -
Distance = c1-c2
Suppose we have the points P and Q on a number line where the coordinate of P=p and the coordinate of Q=q. Then the Ruler Postulate will tell how to find the length PQ. The coordinates will be subtracted and the absolute value will be taken.
PQ = p-q or q-p
