Postulate #2

If there is a line, then it contains at least two points.

Opposite of Unique Line Postulate.

Unique Plane Postulate

If there are three noncollinear points, then they determine a plane.

Think "three".

Postulate #4

If there is a plane, then it contains at least three noncollinear points.

Opposite of Unique Plane Postulate.

Postulate #5

If the points are in the plane, the line is in the plane

Relationship between points, line and plane.

Postulate #6

If two planes intersect, their intersection is a line.

Think classroom.

Ruler Postulate

Points A, B and C lie on a line.
AC  AB = BC 

Segment Addition Postulate

Points A, B and C lie on a line.
AB + BC = AC 

Protractor Postulate

Two angles (angle 1, angle two) share a ray and form one larger angle (angle 3).
Angle 3  Angle 2 = Angle 1 

Angle Addition Postulate

Two angles (angle 1, angle two) share a ray and form one larger angle (angle 3).
