Alternate interior angles are formed when a transversal intersects two parallel lines. In this case, the given angles are alternate interior angles because they are on opposite sides of the transversal and are inside the two parallel lines.
30.
Identify each pair of angles as corresponding, alternate interior, alternate exterior, sameside interior, vertical, or linear.
Correct Answer
C. Corresponding
Explanation
The given answer "Corresponding" is correct because when two lines are crossed by another line (known as a transversal), the angles that are in the same position on each line are called corresponding angles. In this case, the angles mentioned in the question are corresponding angles because they are in the same position on each line that is being crossed by the transversal.
