General objective of this lecture is to present on Alternate Interior Angles. When two lines are crossed by another line (called the Transversal): The pairs of angles on opposite sides of the transversal but inside the two lines are called Alternate Interior Angles. Two angles that lie between parallel lines on opposite sides of the transversal. Two angles that lie outside parallel lines on opposite sides of the transversal. Two angles that lie between parallel lines on the same sides of the transversal.
