    • Addition property
    • Subtraction property
    • Multiplication Property
    • Division Property
  2. if a=b then a + c = b+ c
    Addition property
  3. a=b 
    a- c= b-c
    Subtraction property
  4. a=b
    ac=bc
    Multiplication property
  5. a=b
    a/c=b/c
    Division property
  6. Any real number is what?
    Equal to itself (reflexive property)
  7. _                              _
    AB (congruent sign) AB
    Reflexive Property
  8. a=a
    Reflexive Property
  9. What property can you switch the two sides of an equation?
    Symmetric Property
  10. <A=m<B then m<B=m<A
    Symmetric Property
  11. a=b
    b=a
    Symmetric property
  12. If a=b and b=c then a=c
    Transitive Property
  13. If AB=BC and BC=AC then AB=AC
    Transitive Property
  14. If two things are equal to the same thing they are equal to each other
    Transitive Property
  15. This property says that if two things are equal then one may be substituted in place of the other
    Substitution Property
  16. x=y
    6x=10
    6y=10
    Substitution property
  17. AB=15
    then AB + 5= 20
    Addition Property
  18. m<K =20 and m<J=m<K + m<L
    then m<J = 20= m<L
    Substitution property
  19. if AB+CD=JK then JK=AB+CD
