|
|
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

|
|
division property of equality
|
if a=b and c=d, then a/c=b/d
|
|
|
substitution property of equality
