Chapter 2 Review

Front

What is the Reflexive Property of Equality?

Back

For any number a, a = a. This property states that any quantity is equal to itself.

Front

What does the Transitive Property of Equality state?

Back

If a = b and b = c, then a = c. This property allows us to conclude equality through a chain of equalities.

Front

Define a Counterexample.

Back

A specific example that proves a conjecture to be false.

Front

What does the Vertical Angles Theorem state?

Back

If two angles are vertical angles, then they are congruent (equal in measure).

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 Symmetric Property of Equality?

Back

If a = b, then b = a. This property states that equality can be reversed.

Front

What is the Substitution Property of Equality?

Back

If a = b, then b can be substituted for a in any expression.

Front

What is the definition of Congruent Angles?

Back

Two angles are congruent if they have the same measure.

Front

What is the definition of a Postulate?

Back

A statement accepted as true without proof, serving as a basis for reasoning.

Front

What is the definition of an Angle Bisector?

Back

An angle bisector is a ray that divides an angle into two congruent angles.
