Front

What is the Subtraction Property of Equality?

Back

If two quantities are equal, subtracting the same amount from both sides maintains the equality.

Front

What does the Vertical Angles Theorem state?

Back

Front

What is the Substitution Property in geometry?

Back

If two quantities are equal, one can be substituted for the other in any expression.

Front

Where do statements go in a geometric proof?

Front

What is the Addition Property of Equality?

Back

If two quantities are equal, adding the same amount to both sides maintains the equality.

Front

What is the Multiplication Property of Equality?

Back

If two quantities are equal, multiplying both sides by the same non-zero number maintains the equality.

Front

What is the Division Property of Equality?

Back

If two quantities are equal, dividing both sides by the same non-zero number maintains the equality.
