Given: Two parallel lines p and q, and a transversal intersecting them.
Required: Pair of corresponding angles.
Explanation:
Corresponding angles are the angles that occupies same relative position when two parallel lines are intersected by a transversal.
So here, first pair of corresponding angles is ∠3 and ∠1.
Second pair is ∠4 and ∠2.
Final Answer: Pair of corresponding angles are ∠3 and ∠1; ∠4 and ∠2.
