Explanation:
Alternate Interior Angles
Alternate interior angles are the angles formed on the opposite sides of the transversal. In other words, when two parallel lines are intersected by a transversal, eight angles are formed. Among these, the angles that lie on the inner side of the parallel lines but on the opposite sides of the transversal are known as the alternate interior angles.
What are Alternate Interior Angles?
When two parallel lines are crossed by a transversal, the pair of angles formed on the inner side of the parallel lines, but on the opposite sides of the transversal are called alternate interior angles. These angles are always equal. This can also be understood in another way. The alternate interior angles can prove whether the given lines are parallel or not. If these angles are equal, then the given lines which are crossed by a transversal are said to be parallel.
