postulates Flashcards
segment addition postulate
if B is between A and C then AB+ BC = AC. if AB + BC = AC then B is between A and C
Angle addition postulate
if P is in the interior of RST the the sum of RSP and PST equal RST
two point postulate
through any two point there exist exactly one line
line point postulate
a line contains at least two points
line intersection postulate
if two lines intersect then their intersection is exactly one point
three point postulate
through any three non collinear points there exist exactly one plane
plane point postulate
a plane contains at least three non collinear points.
plane line postulate
if two points lie in a plane then the line containing them lies in the plane.
plane intersection postulate
if two planes intersect then their intersection is a line.
linear pair postulate
if two angles form a linear pair then they are supplementary
parallel postulate
if there is a line and a point not on the line then there is exactly one line through the point parallel to the given lines
perpendicular postulate
if there is a line and a point not on the line then there is exactly one line through the point perpendicular to the given line
translation postulate
a translation is a rigid motion
reflection postulate
a reflection is a rigid motion
rotation postulate
a rotation is a rigid motion
