Front

Congruent Complements Theorem

Back

If two angles are complementary to the same angle (or to two congruent angles), then the two angles are congruent.

Front

Congruent Supplements Theorem

Back

If two angles are supplementary to the same angle (or to two congruent angles), then the two angles are congruent.

Front

Right Angle Theorem

Back

If two angles are right angles, then they are congruent.

Front

Linear Pair Theorem

Back

If two angles form a linear pair, then they are supplementary.

Front

Angle Addition Postulate

Back

m∠1 + m∠2 = m∠3

Front

Segment Addition Postulate

Front

Reflexive Property of =

Back

a = a

Front

Symmetric Property of =

Back

If a = b, then b = a.

Front

Transitive Property of =

Back

If a = b and b = c, then a = c.

Front

Distributive Property

Back

If a(b + c) then ab + ac.
