 a=a reflexive property if a=b then b=a symmetric property if a=b and b=c, then a=c transitive property if a =b, then a+c = b+c addition property of equality if a=b, then a-c= b-c subtraction property of equality if a=b, then a times c= b times c AxC = BxC multiplication property of equality if a=b, then a/c=b/c (c does not equal 0) division property of equality if a=b, then you may replace b with a in any expression substitution property of equality a(b+c)=ab+ac distribution property Through any 2 points, there is exactly one line postulate 2-1 Through any 3 collinear points there is exactly 1 plane. Postulate 2-2 A line contains at least 2 points Postulate 2-3 A plane contains at least 3 points, not all on the same line Postulate 2-4 If 2 points lie on a plane then the entire line containing those 2 points lies in that plane Postulate 2-5 Two lines intersect in a line Postulate 2-6 Two planes intersect in a line Postulate 2-7 IF M is midpoint of segment AB, then segment AM is congruent to segment MB Midpoint theorem The points on any line or line segment can be paired with real numbers so that, given any 2 points, A and B on a line, A corresponds to zero, and B corresponds to a positive real number Ruler Postulate If A, B, and C are collinear and B is between A and C, then AB+BC= AC. If AB+BC=AC, then B is between A and C.
