GEOMETRY POSTULATES

Question 1

Ruler Postulate

Answer 1

The points on a line can be matched one to one with the real numbers. The real number that corresponds to a point is the coordinate of the point. The distance between points A and B, written as AB, is the absolute value of the difference between the coordinates of A and B.

Question 2

Segment Addition Postulate

Answer 2

If B is between A and C, then AB + BC = AC, then B is betwen A and C.

Question 3

Protactor Postulate

Answer 3

Consider OB and a point A on one side of OB. The rays of the form OA can be matched one to one with rhe real numbers from o to 180. The measure of Angle AOB is equal to the absolute value of the diference between the real numbers for OA and OB.
