What is the Reflexive Property of Congruence?

Back

For any segment AB, AB is congruent to AB.

Front

What is the Symmetric Property of Congruence?

Back

If segment AB is congruent to segment CD, then segment CD is congruent to segment AB.

Front

What is the Transitive Property of Congruence?

Back

If segment AB is congruent to segment CD and segment CD is congruent to segment EF, then segment AB is congruent to segment EF.

Front

What is the Substitution Property?

Back

If two segments are congruent, one can be substituted for the other in any expression.

Front

What is the Addition Property of Equality?

Back

If a = b, then a + c = b + c for any c.
