Answer: Hence, ∠A and ∠C are vertically opposite angles.
Step-by-step explanation:
Since we have given that
q and p are two parallel lines.
and r is the transversal line which cut the two parallel lines p and q.
Then we can see that
∠A and ∠C are vertically opposite angles.
As we know that vertically opposite angles are those angles which are opposite to each other when two lines intersect each other.
Hence, ∠A and ∠C are vertically opposite angles.
