The points of a line can be put into onetoone correspondence with the real numbers so that the distance between any two points is the absolute value of the difference of the corresponding numbers.

ruler postulate

AB= ab
<(A)(B)> 

If three points A, B, and C are collinear and B is between A and C, then AB + BC = AC. The three points must share an endpoint

segment addition postulate

(A)(B)(C)


Given line AB and a point O on line AB. Consider rays OA and OB, as well as all the other rays that can be drawn, with O as an endpoint, on one side of line AB. These rays can be paired with the real numbers between 0 and 180 in such a way that:
1. Ray OA is paired with 0, and ray OB is paired with 180. 2. If ray OR is paired with a and ray OQ is paired with b, then m <ROQ =  a  b . 
protractor postulate

If point B is in the interior of AOC, then mAOB + mBOC= mAOC
If AOC is a straight angle, then mAOB + mBOC= 180 (must share an endpoint)
