The true conditional statement, "If - (ABC) = MZABD, then I ZABC = 2(M ZABD)," illustrates which property of equality?

The given true conditional statement "If - (ABC) = MZABD, then I ZABC = 2(M ZABD)," illustrates the property of equality known as the Multiplication Property of Equality.

The Multiplication Property of Equality states that if you multiply both sides of an equation by the same non-zero number, then the equality still holds. In the given statement, we are multiplying both sides of the equation "I ZABC = MZABD" by the non-zero number 2. This shows the Multiplication Property of Equality.
