Answer the given questions about the indicated examples of this section.

In Example 3(b), if ∠POR = 35° in Fig. 2.4, what is the measure of ∠QOR?

Data from Example 3(b)

In Fig. 2.4, we see that ∠POQ is a right angle, or ∠POQ = 90°. Because ∠POR + ∠ROQ = ∠POQ = 90°, ∠POR is the complement of ∠ROQ (or ∠ROQ is the complement of ∠POR).
