Postulates 1-1 through 1-8
(Postulate 1-7) Protractor Postulate
Every angle can be measured between 0 and 180 degrees
(Postulate 1-3) If two distinct planes intersect then they...
intersect at exactly one line.
(Postulate 1-2) If two lines intersect then they...
intersect at exactly one point.
(Postulate 1-6 Segment Addition Postulate) If point B is between A and C and they are collinear than...

there is exactly one plane.
Postulate 1-8) Angle Addition Postulate
m<AOB + m<BOC = m<ADC (FOR ADJACENT ANGLES ONLY)
