Answer:The corresponding angles postulate states that if two parallel lines are cut by a transversal, the corresponding angles are congruent. Parallel lines m and n are cut by transversal l above, forming four pairs of congruent, corresponding angles: ∠1 ≅ ∠5, ∠2 ≅ ∠6, ∠3 ≅ 7, and ∠4 ≅ ∠8.
Step-by-step explanation:Corresponding angles are the angles that appear to be in the same relative position in each group of four angles. In Figure , ∠l and ∠5 are corresponding angles. Other pairs of corresponding angles in Figure are: ∠4 and ∠8, ∠2 and ∠6, and ∠3 and ∠7.
