Found inside the intersected lines. (interior)

They are also opposite sides of the transversal.

Alternate Interior angles created by a Transversal

Angles (** 2 and 5**) and (**3 and 6**) are consecutive interior angles are their angle measure equals 180 degrees ( supplementary)

If the lines cut by the transversal are non- parallel, then the alternate interior angles have no angle relationship.

If a transversal intersects two parallel lines, then each pair of alternate interior angles are equal.

In order to help remember the difference between** interior **and** exterior** angles, I envision a hamburger.

The** alternate interior angles** are inside the bun and the **alternate exterior angles** are found outside the bun.

Transversal

Exterior ( outside the bun)

Interior (inside the bun)

A transversal is a line that intersects two or more lines. The lines do not have to be parallel.

When a transversal intersects two parallel lines it creates both alternate interior and exterior angles.

Angles created on opposite sides of the** transversal **and **inside **the parallel lines are called **alternate interior angles**. Alternate interior angles have the same degree measure when the two lines cut by the transversal are parallel.

If the lines cut by the transversal are** non- parallel,** then the alternate interior angles have no angle relationship.
