Math properties
Properites and postulates for Geometry
Term | Definition |
---|---|
Transitive Property of Equality/Congruence | If a=b and b=c, then a=c, If AB is congruent to CD and CD is congruent to EF, then AB is congruent to EF |
Symmetric Property of Equality/Congruence | If a=b then b=a. If measure of angle A= measure of angle B, then measure of angle B= measure of angle A |
Reflexive Property of Equality/Congruence | a=a. AB is congruent to AB |
Distributive Property | a(b+c)= ab+ac or a(b-c)= ab-ac |
Addition Property | If a=b, then a+c=b+c |
Subtraction Property | If a=b, then a-c=b-c |
Multiplication Property | If a=b, then ac=ab |
Division Property | If a=b and c does not equal 0, then a/c=b/c |
Substitution Property | If a=b, then let b substitute a in any situation |
Commutative Property | 5+3=3+5 |
Segment Addition Postulate | AB+BC=AC |
Angel Addition Postulate | measure of angle AOB+ measure of angle BOC= measure of angle AOC |
