The correct option is same side interior angles.
We know that when the two angles sums to 180 degrees then the angles are supplementary to each other.
Let us suppose x and y are supplementary to each other. Then we have
[tex]x+y =1 80[/tex]
Now, we know that when two parallel lines are cut by a transversal, then consecutive interior angles adds up to 180 degrees.
Hence, same side interior angles pairs are supplementary.
C is the correct option.
Answer:
option C
Step-by-step explanation:
correct answer is option C
Angles are given in the diagram attached below.
alternate interior angles are ∠1 and ∠3 , ∠2 and ∠4 and they are equal to each other.
alternate exterior angles are ∠1 and ∠8 , ∠2 and ∠7 they are equal to each other.
corresponding angles are ∠1 and ∠5 , ∠2 and ∠6 they are equal to each other.
where as same side interior angles are supplementary means
∠4 + ∠5 = 180°
