contains at least 2 points
contains at least 3 noncollinear points
contains at least 4 noncoplanar points
through any 2 points there is exactly 1 line
- through any 3 points there is at least 1 planethrough any 3 noncollinear points there is exactly 1 plane
if 2 points are in a plane, then the line that contains the points is in that plane
- If 2 lines intersect, then they intersect in exactly one point
- Through a line and a pont not on the line, there is exactly one plane
- If two lines intersect, then exactly one plane contains the lines
segments can be measured
"SEGMENT ADDITION POSTULATE"
If B is between A and C, then AB+BC=AC
angles can be measured
"ANGLE ADDITION POSTULATE"
if point B lies in the interior of angle AOC, then m∠AOC+m∠BOC=m∠AOC.
