Unit 2 Geometry Properties

Front

What is the Transitive Property?

Back

If a = b and b = c, then a = c. It allows us to substitute equal values in equations.

Front

What is the Definition of Congruence?

Back

Two figures are congruent if they have the same shape and size, denoted as MN ≅ PQ if MN = PQ.

Front

What are Supplementary Angles?

Back

Two angles are supplementary if their measures add up to 180 degrees.

Front

What is the Angle Addition Postulate?

Back

If point B is in the interior of angle AOC, then m∠AOB + m∠BOC = m∠AOC.

Front

What is the Definition of Complementary Angles?

Back

Two angles are complementary if their measures add up to 90 degrees.

Front

What is the Addition Property?

Back

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

Front

What is the Subtraction Property?

Back

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

Front

What is the Reflexive Property?

Back

Any quantity is equal to itself, a = a.

Front

What is the Symmetric Property?

Back

If a = b, then b = a.

Front

What is the Complements Theorem?

Back

If two angles are complementary to the same angle, then they are congruent.
