Algebraic and Geometric Proofs Practice

Front

What is the Substitution Property of Equality?

Back

If a = b, then a can be replaced by b in any equation or expression.

Front

What is the Transitive Property of Equality?

Back

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

Front

What is the Addition Property of Equality?

Back

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

Front

What is the Subtraction Property of Equality?

Back

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

Front

What is the Division Property of Equality?

Back

If a = b and c ≠ 0, then a/c = b/c.

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 are Supplementary Angles?

Back

Two angles whose measures add up to 180 degrees.

Front

What is the Definition of Midpoint?

Back

A point that divides a segment into two equal parts.

Front

What is the Segment Addition Postulate?

Back

If B is between A and C, then AB + BC = AC.

Front

What is the Vertical Angles Theorem?

Back

Vertical angles are congruent.
