angle addition postulate

part of the angle+other part of the angle=whole angle
part+part=whole 

ruler postulate

the distance between any two points is
BA or AB 

segment addition postulate

If B is between A and C, then
AB+BC=AC part+part=whole 

Addition property of equality

can add equivalent things to both sides of an equation
If a=b and c=d, then a+c=b+d If AB+CD and EF+GH, then AB+EF=CD+GH 

subtraction property of equality

can subtract equivalent things from both sides of an equation
If a=b and c=d, then ac=bd 

multiplication property of equality

can multiply equivalent things on both sides of an equation
If a=b and c=d then ac=bd 

division property of equality

if a=b and c=d, then a/c=b/d


substitution property of equality

can substitute equivalent things
If a=b and 2a=5, then 2b=5 

reflexive property of equality

a=a
AB=AB 

reflexive property of congruency

segment AB is congruent to segment AB


symmetric property of equality

AB=BA


symmetric property of congruency

segment AB is congruent to segment BA


transitive property

If a=b and b=c, then a=c


distributive property

a(b+c)=ab+ac
