Math properties

Properites and postulates for Geometry

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

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:
