Alternate Interior Angles Theorem with Parallel Lines

The video tutorial explains the concept of exterior angles, focusing on alternate exterior angles formed by parallel and non-parallel lines. It highlights that alternate exterior angles are equal in measure when lines are parallel. An example is provided to demonstrate this property, showing that the measure of angle 8 is equal to the measure of angle 1.

What can we determine about alternate exterior angles when dealing with parallel lines?

In what scenarios can we determine alternate exterior angles with non-parallel lines?

How do alternate exterior angles relate to each other when the lines are parallel?

Why is it important to remember that alternate exterior angles are located outside the parallel lines?

What is the significance of the measure of angle 8 in relation to angle one?
