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 = bc

Division Property

If a = b, then a/c = b/c

Substitution Property

If a = b, you may relace a with b in any true equation containing a and the resulting equation will still be true.

Reflexive Property

For any real number a, a = a.

Symmetric Property

For all real numbers a and b, if a =b, then b = a.

Transitive Property

For all real numbers a, b, and c, if a = b and b = c, then a = c.

Reflexive Property

Figure A is congruent to figure A

Symmetric Property

If figure a is congruent to figure b, then figure b is congruent to figure a.

Transitive Property

If figure a is congruent to figure b, and figure b is congruent to figure c, then figure a is congruent to figure c.
