Exercise 15 Page 288

Think of each piece as their own expressions: a, b, and c.

Transitive Property

Practice makes perfect
We want to identify the Property of Equality being demonstrated by the given equations. In this case, we are given three equations.

AB = BC BC = CD AB = CD This demonstrates the Transitive Property of Equality. l a = b b = c ⇒ a = c
