Postulate 2
if two distinct lines intersect, then they intersect in exactly one point
Postulate 3
if two distinct planes intersect, then they intersect in exactly one line
Postulate 4
through any three noncollinear points, there is exactly one plane
Postulate 5

contains at least four points not all in one plane.
Postulate 6
Through any two points there is exactly one line.
Postulate 7

there is exactly one plane.
Line
made up of points and has no thickness or width
Point
a location
Plane
a flat surface made up of points that extend infinitely
Intersection
geometric figures that is a set point in common
Space
boundless 3D set of all points
Locus
set of points that satisfy a particular condition
Line segment
segment of a line has two end points
Betweenness of points
the points between the endpoints
