Question

problem 10: (lesson 13)
from this given statement, select the definition, property, postulate, or theorem that justifies the prove statement.
given: ac = ig
prove: ac + ci = ig + ci

Explanation:

The Addition Property of Equality states that if \(a = b\), then \(a + c=b + c\). Here, \(a = AC\), \(b = IG\) and \(c = CI\). Given \(AC = IG\), adding \(CI\) to both sides of the equation results in \(AC + CI=IG + CI\).

Answer:
