The pair of angles that are alternate interior angles are angle 5 and angle 6. Angle 16 and and Angle 17. The correct options are option B and E.
What is Alternate Interior Angle?
Alternate interior angles are a pair of angles that are formed when a transversal intersects two lines. These angles are located on opposite sides of the transversal and are positioned between the two lines being intersected.
To visualize alternate interior angles, imagine two parallel lines being intersected by a third line called a transversal. The alternate interior angles are formed on the inside of the parallel lines and on opposite sides of the transversal.
