Linear Pair Postulate (Postulate 1-9)
|
If two angles form a linear pair then they are supplementary.
|
|
Angle Addition Postulate (Postulate 1-8)
|
If point B is in the interior of angle AOC, then the measure of angle AOB plus the measure of angle BOC equals the measure of angle AOC.
|
|
Protractor Postulate (Postulate 1-7)
|
Consider ray OB and a point A on one side of ray OB. Every ray of the form ray OA can be paired one to one with a real number from 0 to 180.
|
|
Segment Addition Postulate (Postulate 1-6)
|
If three points A,B, and C are collinear and B is between A and C, then AB+BC=AC
|
|
Ruler Postulate (Postulate 1-5)
|
Every point on a line can be paired with a real number. This makes a one-to-one correspondence between the points on the line and the real numbers. The real number that corresponds to a point is called the coordinate of the point

Through any three non-collinear points there is exactly one plane |
|
Postulate 1-3
If two distinct planes intersect, then they intersect how many lines? |
exactly 1
If two distinct planes intersect, then they intersect in exactly one line |
