Which pairs represent same-side interior angles or consecutive interior angles?

The correct answer is: {∠1 , ∠5} ,{∠2,∠6},{∠3,∠7} and {∠4 ,∠8} are the 4 pairs of Consecutive interior angles.

Explanation :-
Consecutive interior angles are the pairs of angles that are between two lines and on the same side of the line cutting through the two lines.
{∠1 , ∠5} ,{∠2,∠6},{∠3,∠7} and {∠4 ,∠8} are the 4 pairs of Consecutive interior angles
With their respective parallel lines.
