Select the postulate that states points a and b lie in only one line.
postulate 1: a line contains at least two points.
postulate 1a: a plane contains at least three points not all on one line.
postulate 1b: space contains at least four points not all on one plane.
postulate 2: through any two different points, exactly one line exists.
postulate 3: through any three points that are not one line, exactly one plane exists.
postulate 4: if two points lie in a plane, the line containing them lies in that plane.
postulate 5: if two planes intersect, then their intersection is a line.

The  postulate that states points A and B lie in only one line is:

Postulate 2: Through any two different points, exactly one line exists.

Postulate--

A postulate is a statement that is assumed to be trivially true i.e. it does not require any proof. It is a  valid statement that is used to prove some other statements or theorems.It is also known as a axiom.

Among the given postulates the postulate which states that two points A and B will lie in only one line is:

                         Postulate 2

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.

step-by-step explanation: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
