The points on a line can be matched 1:1 with the real numbers. The number that corresponds to a point is called its coordinate.
The distance between points A and B is the absolute value of the difference of the coordinates of A and B. |

Segment Addition Postulate
|
If B is between A and C, then AB + BC = AC.
If AB + BC = AC then B is between A and C. |
|
|
Protractor Postulate
|
Consider angle AOB. The rays of angle AOB can be matched 1:1 with the real numbers from 0 to 180.
The measure of angle AOB is equal to the absolute value of the difference between the real numbers for ray OA and OB. |

|
Angle Addition Postulate
|
Consider angle RST. If P is in the interior of angle RST then the measure of angle RST is equal to the sum of the measures of angle RSP and PST.
