LINE contains at least 2 points PLANE contains at least 3 noncollinear points SPACE contains at least 4 noncoplanar points POSTULATE 6 through any 2 points there is exactly 1 line POSTULATE 7 through any 3 points there is at least 1 planethrough any 3 noncollinear points there is exactly 1 plane POSTULATE 8 if 2 points are in a plane, then the line that contains the points is in that plane THEOREMS: If 2 lines intersect, then they intersect in exactly one pointThrough a line and a pont not on the line, there is exactly one planeIf two lines intersect, then exactly one plane contains the lines "RULER POSTULATE" segments can be measured "SEGMENT ADDITION POSTULATE" If B is between A and C, then AB+BC=AC "PROTRACTOR POSTULATE" angles can be measured "ANGLE ADDITION POSTULATE" if point B lies in the interior of angle AOC, then m∠AOC+m∠BOC=m∠AOC.
