Exercise 8 Page 319

What is the relation between angles ∠ 1 and ∠ 2?

Parallel Lines: r ∥ s
Postulate: Converse of the Corresponding Angles Postulate

Practice makes perfect

Let's begin by highlighting ∠ 1 and ∠ 2 in the diagram.

We can see that ∠ 1 and ∠ 2 are corresponding angles of lines r and s. Also, we are told that they are congruent. Therefore, by the Converse of the Corresponding Angles Postulate, we can conclude that r ∥ s.
