2. Review these properties and state them in your own words

3. Addition property If two values are the same, and the same value is added to both, they will remain equal. If x=3, then x+4=3+4

4. Subtraction Property If two values are the same and you subtract the same amount from both, they will remain the same. If x=7 then x-4=7-4

5. Multiplication Property

6. Division property

7. Reflexive property

8. Symmetric Property If a=b then b=a This allows us to work in any order around the equal sign

9. Transitive property (syllogism) If A=B and B=C then A=C. If two things are equal to the same thing, then they are equal

10. Substitution Property

11. Distributive property

12. Properties of congruence Because equal and congruent have similar meanings, the properties of equality of numbers, can be easily applied as properties of congruent shapes.
