Front

If m<K = m<L, what can we conclude about m<L and m<K?

Back

m<L = m<K (Symmetric Property of Equality)

Front

If A = B, what can we say about 8A and 8B?

Back

8A = 8B (Multiplication Property of Equality)

Front

What is the REASON for the statement: If a = b, then a/c = b/c?

Back

Division Property of Equality

Front

What property is illustrated by the statement AB = AB?

Back

Reflexive Property of Equality

Front

What is the justification for the statement: If a = b and b = c, then a = c?

Back

Transitive Property of Equality

Front

What does the Addition Property of Equality state?

Back

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

Front

What does the Subtraction Property of Equality state?

Back

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

Front

What is the definition of the Reflexive Property of Equality?

Back

For any number a, a = a.

Front

What is the definition of the Symmetric Property of Equality?

Back

If a = b, then b = a.

Front

What is the definition of the Transitive Property of Equality?

Back

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