2. From the diagram shown below, what is the relation between ∠POS and ∠ROQ?

a) ∠POS > ∠ROQ
b) ∠POS < ∠ROQ
c) ∠POS = ∠ROQ
d) ∠POS = 2∠ROQ
View Answer

Answer: c
Explanation: According to theorem 6.1, if two lines intersect each other then vertically opposite angles are equal.
In the given diagram, ∠POS and ∠ROQ are vertically opposite angles, hence they are equal according to theorem 6.1.
