Final answer:
The Transitive Property of Equality states that if two quantities are equal to the same quantity, then they are equal to each other. So, if m∠1 = m∠2 and m∠2 = m∠3, then by the Transitive Property, m∠1 = m∠3. In other words, angle 1 is equal to angle 3.
Step-by-step explanation:
The Transitive Property of Equality states that if two quantities are equal to the same quantity, then they are equal to each other.
So, if m∠1 = m∠2 and m∠2 = m∠3, then by the Transitive Property, m∠1 = m∠3. In other words, angle 1 is equal to angle 3.
This property is commonly used in geometry and algebra to relate equations and solve problems involving angles and other geometric figures.
