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...

AB + BC = AC (The other part of the line plus the other part equals the who part.)

(Postulate 1-4) Through any 3 non-collinear points...

there is exactly one plane.

Postulate 1-8) Angle Addition Postulate

m<AOB + m<BOC = m<ADC (FOR ADJACENT ANGLES ONLY)

(Postulate 1-5 Ruler Postulate) For every point on a line...

there is a real number paired with it (the coordinate).

(Postulate 1-1) Through any two points...

there is exactly one line.
